Troubleshooting
Start with the current version, device architecture, service status and the exact error message. Do not paste passwords, tokens, pairing codes, private keys or full device serial numbers into a ticket.
Cannot sign in
Confirm the NAS address, account and time. NAS desktop, SSH, SMB, ApuConnect and community accounts are separate. Reset only through the supported administrator flow.
Upload or sync failed
Check certificate trust, pairing status, destination permissions, available space and the final hash. ApuSync direct transfer does not silently fall back to cloud relay.
Update failed
Read the update service log, preserve the rollback state and verify the current version before retrying. Do not delete the updater state or force a downgrade.
