Troubleshoot upgrade issues

PMM Server not updating correctly

If PMM Server is not updating correctly, check the container logs for errors:

docker logs pmm-server

If the issue persists, restore from a backup and retry the upgrade. See Restore PMM Server.

Corrupted credentials after encryption key rotation

If you ran pmm-encryption-rotation before upgrading to PMM 3.9.1, TLS/SSL certificates and keys or cloud credentials for some services may be corrupted. Remove and re-add the affected services to recreate them:

pmm-admin remove <service-type> <service-name>
pmm-admin add <service-type> ... # supply the original TLS/cloud credentials
