    Common Reasons the Procore App Stops Working

    1. Weak or Unstable Internet Connection

    The Procore app requires a reliable connection to sync data.
    Poor Wi-Fi, weak cellular signal, or switching between networks can cause the app to freeze, fail to load, or not update.

    If requests are timing out, review Procore Error 408.

    2. Outdated App Version

    Running an old version of the Procore app can cause login failures, syncing problems, or crashes.

    App updates often fix bugs and compatibility issues.

    Always install the latest version from the App Store or Google Play.

    3. Login Session Problems

    If your login session expires or becomes corrupted, the app may fail to load projects or keep redirecting to login.

    If the app keeps sending you back to sign-in, see Procore Login Loop.

    If your account becomes locked, review Procore Account Locked.

    4. Permission or Access Changes

    If your permissions changed recently, the app may open but certain tools will not load.

    If you see access errors, review Procore Permission Denied.

    5. Large File Sync or Upload Problems

    Photos, drawings, and documents may fail to load if the connection is slow or the file is large.

    If uploads fail, review Procore File Upload Failed.

    6. Too Many Requests or Sync Conflicts

    When the app sends too many requests at once, the system may slow down or stop responding.

    If this happens, see Procore Error 429.

    7. Temporary System Issues

    Occasionally the problem is not your device.

    If multiple users cannot use the app at the same time, the system may be under load.

    Check the Procore official status page.

    If services are degraded, the app may not work until performance returns to normal.

    How to Fix the Procore App Not Working

    Follow these steps in order.

    Step 1: Check Your Internet Connection

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

    Step 2: Close and Reopen the App

    Force close the app completely, then open it again.

    This clears temporary session errors.

    Step 3: Log Out and Log Back In

    Logging out resets authentication.

    Use the correct company login link.

    Step 4: Update the App

    Go to the app store and install updates.

    Outdated versions cause many problems.

    Step 5: Restart Your Device

    Restarting clears memory and connection conflicts.

    Step 6: Clear App Cache (Android)

    Settings → Apps → Procore → Storage → Clear Cache

    iPhone users may need to reinstall the app instead.

    Step 7: Reinstall the App

    Delete the app, reinstall, and log in again.

    This fixes most persistent problems.

    Step 8: Wait if System Is Slow

    If the system is under heavy load, the app may not respond until traffic decreases.

    Why App Problems Happen More on Job Sites

    Field devices often have:

    • weak cellular signal
    • shared logins
    • older tablets
    • slow Wi-Fi
    • large photo uploads
    • many users syncing at once

    These conditions increase the chance of app failures.

    Keeping devices updated and using stable connections reduces most problems.

    How to Prevent Future App Issues

    Best practices:

    • Keep the app updated
    • Use strong internet when syncing
    • Avoid uploading very large files on weak signal
    • Log out after password changes
    • Do not share accounts
    • Restart the app if it starts acting slow

    Consistent device maintenance prevents most mobile problems.

    When to Contact Support or Your Admin

    Escalate if:

    • app fails on multiple devices
    • other users have the same problem
    • login works on desktop but not mobile
    • reinstall does not fix it
    • status page shows no outage

    Provide:

    • device type
    • app version
    • screenshot
    • project name
    • time of error

    This helps support identify the cause faster.

  • Procore File Upload Failed: * Fixes That Actually Work

    Procore file upload failed error message

    Procore file upload failed? This issue can stop documents, photos, and important files from being added to your project, causing delays and workflow disruptions.

    The good news is most upload failures are caused by file size limits, connection issues, or app errors — and can be fixed quickly.

    Below are the most common causes and 6 fixes that actually work to get your files uploading again.

    For a complete overview of Procore error types and related fixes, see our Procore Error Codes guide.

    For a complete list of Procore troubleshooting fixes, visit our Procore Errors & Troubleshooting Guide.

    Common Causes of Procore Upload Failures

    1) File Size Is Too Large

    Large PDFs, drawing sets, videos, or high-resolution photos can exceed practical upload limits—especially on slower networks. Even if there isn’t a strict size cap, large uploads are more likely to fail.

    2) Slow or Unstable Internet Connection

    Uploads require a stable connection. Wi-Fi drops, weak signal strength, or congested networks can interrupt the upload before completion.

    This is especially common on job sites where cellular signal fluctuates.

    3) Request Timeout During Upload

    If the upload takes too long, Procore may time out the request and stop the upload attempt.

    If you suspect a timeout scenario, review our guide on Procore Error 408 (Request Timeout).

    4) Unsupported File Type or Corrupted File

    If the file is corrupted or in a format Procore cannot process, the upload may fail immediately or stall during processing.

    5) Zero-Byte (Empty) File

    A file that shows 0 KB / 0 bytes will always fail. This commonly happens when files are dragged from a cloud drive without being downloaded locally first.

    6) Permissions or Access Restrictions

    If your role does not allow uploads in a specific tool (Documents, Photos, Drawings, etc.), you may see a failure message.

    If access seems restricted, review Procore Permission Denied.

    7) Temporary System Load or Maintenance

    During heavy load or maintenance windows, uploads may fail intermittently.

    You can check whether Procore is experiencing broader system issues on the official Procore status page.

    If the platform is degraded, waiting and retrying is often the correct solution.

    How to Fix “Procore File Upload Failed” (Step-by-Step)

    Step 1: Refresh and Retry Once

    Sometimes a single retry resolves a temporary hiccup.

    Step 2: Confirm the File Is Not Empty

    Right-click the file → Properties (Windows) / Get Info (Mac) and confirm size is greater than 0 KB.

    Step 3: Rename the File

    Remove special characters and keep the name simple. Avoid symbols like:

    # % & { } < > * ? / \ | : "

    Step 4: Reduce File Size

    If the file is large:

    • compress PDFs
    • reduce image resolution
    • split large PDFs into smaller files

    Step 5: Switch Networks

    If you’re on jobsite Wi-Fi, try a hotspot or a different network.

    Step 6: Try a Different Browser or Incognito Window

    This rules out browser extensions, cached sessions, and stored credentials interfering with the upload.

    Step 7: Confirm You Have Upload Permissions

    If uploads fail consistently in a specific project/tool, ask the project admin to confirm your permission level.

    Step 8: Wait 10–15 Minutes if the System Is Slow

    If Procore is under load, repeated uploads can fail until the system stabilizes.

    If system errors are occurring at the same time, review Procore Error 503 and Procore Error 500.

    Why Upload Failures Are More Common on Large Projects

    Large projects tend to generate:

    • heavier drawing packages
    • more frequent photo uploads
    • larger PDF submittals
    • more concurrent users

    More activity increases the chance of timeouts, load issues, and user permission conflicts. Establishing standardized naming, file size guidelines, and upload windows can reduce failures dramatically.

    Preventing Future Upload Failures

    Use these best practices:

    • Upload large files on stable networks (wired or strong Wi-Fi)
    • Avoid peak usage times when possible
    • Keep file names simple and consistent
    • Verify file size and integrity before uploading
    • Confirm permissions before deadlines
    • If using cloud storage, download locally before uploading into Procore

    When to Escalate to Admin or Support

    Escalate if:

    • uploads fail across multiple devices and networks
    • multiple users report the same issue simultaneously
    • the status page shows no incident but failures persist
    • the same file fails repeatedly even after renaming/compressing

    Provide:

    • file name and size
    • tool used (Documents, Photos, Drawings, etc.)
    • timestamp
    • screenshot
    • browser/device details
