Troubleshooting

A transfer stalls or never finishes

1. Enable the Activity Log.
2. Reproduce the transfer.
3. Open the Activity Log and copy the entries — they show the pipeline stage where the transfer stopped.

Common causes are low max_execution_time, insufficient memory, or a provider-side rate limit. Reduce Concurrent Workers and retry.

Large files fail to transfer

• Lower the Transfer Chunk Size (e.g. to 4 MB or 1 MB).
• Confirm PHP's memory_limit and max_execution_time are adequate.
• Some providers require chunk alignment (the plugin adjusts automatically for OneDrive's 320 KiB requirement).

"Re-auth session expired" notice

This appears when an OAuth return link outlives its security binding. Simply click Sign in again on the account to create a fresh connection. No account is modified or duplicated by an expired link.

OAuth account connects but shows the wrong identity

Re-authenticate via Edit → Sign in. The verified identity is stored at connection time and updated on re-auth.
