Observed behavior: The system abruptly stops the process and displays an 'Error Uploading File' message, even when testing on different computers, networks, and with varying file sizes.

Solution 1Recommended

Refresh Session and Clear Browser Data

Signing out, clearing cache, and disabling extensions can resolve upload interruptions caused by corrupted session data or browser conflicts.

Upload services heavily rely on active, uncorrupted authentication tokens and stable browser environments. Corrupt cookies or aggressive security extensions often block file transmissions.

Sign out and sign in

Log out of your Adobe account completely, close the window, and sign back in to refresh your active session and authentication tokens.

Clear browser cache

Navigate to your browser's settings, locate the privacy or history section, and clear your cache and cookies.

Disable extensions

Temporarily disable browser extensions, particularly ad blockers, pop-up blockers, and firewall add-ons, then retry the upload.

Test an alternative browser

If the problem continues, open a completely different web browser (e.g., switch from Chrome to Edge) to isolate browser-specific issues.

Supported Browsers: Ensure you are using the latest version of your web browser, as outdated versions may lack support for modern cloud upload protocols.

Solution 2

Test Network Settings and Contact Support

If local troubleshooting fails, the issue may be network-restricted or require backend support from Adobe.
