Common Causes of Procore Sync Errors

1. Weak or Unstable Internet Connection

Sync requires a stable connection.
If your signal drops while uploading photos, drawings, or reports, the data may not reach the server.

If requests are timing out, review Procore Error 408.

---

2. App Not Fully Updated

Older versions of the Procore app may not sync correctly with the current server.

If the mobile app is not working properly, see Procore App Not Working.

---

3. Upload Failed Before Sync

If a file never uploaded, it cannot sync.

This often happens with large photos, PDFs, or weak connections.

If uploads fail, review Procore File Upload Failed.

---

4. Too Many Requests or Heavy Activity

If many users are working at once, the system may delay updates.

This can happen on large projects with many uploads or reports.

If requests are limited, see Procore Error 429.

---

5. Permission or Access Changes

If your permissions changed, data may not appear even though it exists.

If you see access errors, review Procore Permission Denied.

---

6. Cached Data on Device

Phones and tablets may show old data until the app refreshes.

Cached data can make it look like sync failed even when the server updated correctly.

---

7. Temporary System Load

During heavy usage or maintenance, sync may slow down.

Check the Procore official status page.

If services are degraded, syncing may resume once performance stabilizes.

---

How to Fix Procore Sync Errors (Step-by-Step)

Step 1: Check Internet Connection

• Move to stronger signal
• Switch Wi-Fi / cellular
• Restart router if needed

Step 2: Refresh the Tool or Screen

Pull down to refresh in the app
or reload the page in the browser.

Step 3: Close and Reopen the App

Force close the app completely, then reopen.

This clears temporary sync problems.

Step 4: Log Out and Log Back In

Logging out resets authentication and forces new sync.

If login fails, see Procore Login Loop.

If account locks, see Procore Account Locked.

---

Step 5: Update the App or Browser

Install updates to avoid compatibility problems.

Old versions often cause sync errors.

Step 6: Wait a Few Minutes

Large uploads or reports may take time to process.

Sync delays do not always mean failure.

Step 7: Try Another Device

If the data appears on one device but not another, the issue is likely local.

Step 8: Confirm Permissions

If data exists but you cannot see it, your role may not allow access.

Admins can verify tool permissions quickly.

Why Sync Errors Happen More on Large Projects

Large projects often have:

• many users working at once
• large photo uploads
• frequent drawing updates
• multiple integrations
• mobile + desktop users

More activity increases the chance of sync delays.

Setting upload guidelines and using strong connections reduces most problems.

---

How to Prevent Sync Problems

Best practices:

• upload files on stable internet
• keep app updated
• avoid closing app during upload
• refresh after major updates
• confirm permissions before reporting missing data
• avoid working offline too long

Consistent habits reduce sync issues significantly.

---

When to Contact Support or Your Admin

Escalate if:

• data never syncs after several minutes
• multiple users see different data
• uploads complete but do not appear
• app and desktop show different results
• status page shows no outage but sync fails

Provide:

• project name
• tool used
• screenshot
• time of update
• device used

This helps identify the sync failure faster.

Frequently Asked Questions

What is a Procore sync error?

A Procore sync error occurs when data between your device (usually mobile) and Procore’s servers fails to update properly, resulting in missing, delayed, or unsaved information.

Why is my Procore data not syncing?

Common causes include:

• poor or unstable internet connection
• offline work not properly syncing
• app or browser issues
• server delays
• conflicts between local and server data

How do I fix a Procore sync error?

Why is my data missing after syncing?

This can happen due to:

• sync conflicts between versions
• incomplete uploads
• overwritten data
• failed background sync processes

Can multiple users cause sync conflicts?

Yes. If multiple users edit the same item at the same time, it can create conflicts that result in sync errors.

Why is sync taking a long time?

Possible reasons include:

• large amounts of data being uploaded
• slow internet connection
• server delays
• background processes on the device

Will reinstalling the app fix sync issues?

In many cases, yes. Reinstalling can clear corrupted data and reset the sync process.

Can outdated apps cause sync errors?

Yes. Older versions may not communicate properly with Procore’s current system, leading to sync failures.

What Is a Procore Login Loop?

A Procore login loop occurs when the system repeatedly sends you back to the login page after entering your credentials instead of allowing access to the dashboard. This usually happens when authentication fails to complete correctly, even though the username and password are valid.

Instead of logging in, the page refreshes, redirects, or reloads continuously.

Login loops are typically caused by browser session problems, expired authentication tokens, incorrect login portals, or company security settings.

Common Causes of Procore Login Loop Errors

1. Cached Login Data or Cookies

Old session cookies can conflict with new login attempts, causing Procore to repeatedly send you back to the sign-in screen.

2. Expired Authentication Session

If your session times out or becomes invalid, Procore may not complete the login process correctly.

3. Incorrect Login Portal or SSO Link

Many companies use custom login portals or single sign-on (SSO). Logging in from the wrong URL can cause redirect loops.

4. Multiple Accounts or Saved Credentials

If your browser auto-fills the wrong email or password, Procore may reject the session but keep retrying.

If your account becomes locked after repeated attempts, see Procore Account Locked.

5. Browser Extensions or Security Settings

Ad blockers, script blockers, or strict privacy settings can prevent login tokens from being stored.

6. Permission or Access Changes

If your account access changed recently, the login may succeed but fail to load the dashboard.

If access errors appear after login, see Procore Permission Denied.

7. Temporary System Issues

During heavy load or maintenance, login services may not respond correctly.

Check Procore’s official system status here.

If the system is degraded, waiting is often the correct solution.

How to Fix a Procore Login Loop (Step-by-Step)

Step 1: Clear Browser Cache and Cookies

This fixes most login loops.

Chrome / Edge:

• Settings → Privacy → Clear browsing data
• Select cookies + cached files
• Restart browser

Step 2: Try Incognito / Private Mode

Private mode ignores stored cookies and extensions.

If login works there, the issue is cached data.

Step 3: Use the Correct Login Page

Always log in using your company’s official Procore link or SSO portal.

Avoid using old bookmarks.

Step 4: Disable Browser Extensions Temporarily

Extensions can block authentication scripts.

Disable:

• ad blockers
• script blockers
• privacy tools

Then try again.

Step 5: Log Out of All Sessions

If you are logged in on multiple devices, sessions may conflict.

Log out everywhere, then log in again.

Step 6: Try Another Browser or Device

This helps determine if the issue is local or account-related.

Step 7: Wait and Retry Later

If login services are under load, retrying later may resolve the issue.

If errors appear during login requests, review Procore Error 408 or Procore Error 429.

Why Login Loops Happen More on Large Projects

Large companies often use:

• Single sign-on systems
• Multi-factor authentication
• Company security policies
• Multiple login domains

These increase the chance of session conflicts, especially after password changes or role updates.

Standardizing login procedures across teams reduces login failures.

---

How to Prevent Future Login Loop Issues

Best practices:

• Use the same login link every time
• Avoid saving outdated passwords
• Clear cache after password changes
• Keep browser updated
• Avoid logging in on many devices at once
• Use company-approved login portals

Consistent login habits reduce authentication errors.

---

When to Contact Support or Your Admin

Escalate if:

• login loop continues after clearing cache
• multiple users cannot log in
• account works on one device but not another
• login fails after password reset
• system status shows no outage but issue continues

Provide:

• screenshot
• browser used
• login URL
• timestamp
• user email

This helps identify authentication failures faster.

Frequently Asked Questions

What is a Procore login loop?

A Procore login loop happens when you successfully enter your credentials but are repeatedly redirected back to the login page instead of accessing your account.

What causes a Procore login loop?

Common causes include:

• browser cache or cookie issues
• expired or corrupted session data
• incorrect saved login credentials
• browser extensions interfering with login
• SSO (Single Sign-On) configuration issues

How do I fix a Procore login loop?

Try the following steps:

1. clear browser cache and cookies
2. close and reopen your browser
3. try logging in using an incognito/private window
4. disable browser extensions temporarily
5. try a different browser or device
6. log out of any SSO provider and retry

Can cookies cause a login loop in Procore?

Yes. Corrupted or outdated cookies are one of the most common causes of login loops.

Does using SSO cause login loop issues?

It can. If your company uses SSO (such as Microsoft or Okta), a misconfiguration or expired session can trigger a login loop.

Why does the login page keep refreshing after I enter my credentials?

This usually indicates a session issue where Procore cannot properly establish or maintain your login state.

Will resetting my password fix a login loop?

Not typically. Login loops are usually related to session or browser issues rather than incorrect passwords.

Can browser extensions cause login problems?

Yes. Extensions such as ad blockers, security tools, or script blockers can interfere with authentication.

Why does the login loop only happen on one device?

This usually means the issue is tied to that device’s browser, cache, or stored credentials.

When should I contact Procore Support?

Contact support if:

• the issue persists across multiple browsers and devices
• multiple users are experiencing the same problem
• the issue is related to SSO configuration
• you cannot access your account after all troubleshooting steps

What Does “Procore Account Locked” Mean?

A Procore account locked error means the system has temporarily disabled login access for a user. This typically occurs after multiple failed login attempts or when security protections detect suspicious activity. The lock is designed to protect project data and prevent unauthorized access.

Unlike system errors such as 500 or 503 that relate to platform issues, an account lock is almost always triggered by authentication or security safeguards.

If your Procore account locked message appeared unexpectedly, it usually means the platform detected multiple login attempts or authentication conflicts. A locked account does not indicate a system failure — it simply means the security system temporarily restricted access.

For a full overview of Procore system errors and access issues, see our complete Procore Error Codes guide.

Why Procore Locks Accounts

Procore automatically locks accounts to prevent unauthorized login attempts. Common triggers include:

Multiple Incorrect Password Attempts

Entering the wrong password several times in a row can activate security protections that temporarily block access.

Expired or Changed Credentials

If your company recently updated password policies or security settings, saved credentials may no longer be valid.

Suspicious Login Activity

Logins from new devices, locations, or IP addresses may trigger security verification systems.

Browser Auto-Fill Errors

Auto-saved passwords can sometimes submit outdated credentials repeatedly without the user realizing it.

Company Security Policies

Some organizations enforce strict login controls or single sign-on requirements that can trigger temporary locks.

---

How to Unlock a Procore Account

Follow these steps in order to regain access quickly:

Step 1: Wait a Few Minutes

Many temporary locks automatically reset after a short cooldown period.

Step 2: Reset Your Password

Use the “Forgot Password” link on the login screen to generate a new login credential.

If your Procore account locked warning continues appearing after a password reset, the issue may be related to cached credentials or authentication conflicts rather than incorrect login details.

Step 3: Clear Saved Credentials

Delete stored passwords in your browser before trying again to prevent auto-fill errors.

Step 4: Confirm Correct Login URL

Make sure you are signing in through your company’s correct Procore login page or SSO portal.

Step 5: Try a Different Browser

Testing login in another browser helps determine whether cached data is causing the issue.

Step 6: Contact Your Administrator

If the account remains locked, a project or company admin can manually unlock it.

---

When the Problem Is Not User-Related

Although rare, login issues can sometimes occur due to platform or session issues rather than incorrect credentials. If multiple users are suddenly unable to log in, the issue may be system-wide rather than account-specific.

You can verify whether Procore is experiencing a broader outage by checking the official Procore system status page.

If system services are degraded, login access may return once performance stabilizes.

---

Account Locked vs Other Procore Errors

It’s helpful to distinguish Procore Account Locked error from other common issues:

• Account Locked → Security or authentication restriction
• 429 Error → Too many requests sent
• 408 Error → Request timed out
• 500 Error → Server malfunction

Knowing whether you’re dealing with authentication, network, or server problems determines the correct troubleshooting path.

---

How Long Does a Procore Account Stay Locked?

Duration depends on the cause:

• Temporary security lock → usually resolves within minutes
• Password attempt limit → unlocks after reset or wait period
• Admin-restricted access → requires manual unlock
• SSO authentication issue → resolves after credential verification

Most standard lockouts are short-term safeguards rather than permanent restrictions.

---

Preventing Future Account Lockouts

You can reduce the likelihood of repeated Procore Account Locked errors by following these best practices:

• Use a password manager instead of browser auto-fill
• Avoid repeated login attempts if unsure of password
• Update saved credentials after password changes
• Use company-approved login portals
• Confirm correct email address is used
• Avoid logging in through outdated bookmarks

Stable authentication habits significantly reduce login disruptions.

---

Why Large Teams Experience Lockouts More Often

Organizations with many users frequently see more login-related issues because:

• Password policies change regularly
• New users are added quickly
• Multiple login systems may be used
• Access permissions vary across projects

Establishing clear login procedures and credential management standards can reduce lockouts across teams.

---

When to Contact Support or Your Administrator

Escalate the issue if:

• Password reset does not restore access
• Lock persists longer than 15 minutes
• Other team members experience the same problem
• Your account was locked unexpectedly

Provide:

• Username or email
• Timestamp of last login attempt
• Screenshot of message
• Device/browser used

Accurate information allows administrators to resolve access issues faster.

Most cases of a Procore account locked message are resolved quickly once credentials are verified and login attempts are spaced out.
