Where I find the logs in portainer? Can't find it..

Configuration in the docker compose file:

  • "USE_SYSLOG=true"
  • "LOG_LEVEL=info"
  • "EXTENDED_LOGGING=true"

I'm not using Portainer, so can't help with that. But you can also configure a LOG_FILE (the path should be from the containers view, like /data/vaultwarden.log).
github.com/dani-garcia/vaultwarden@4352fffeec/.env.template (L402)

Since you are using MariaDB my guess is that this is a duplicate of https://github.com/dani-garcia/vaultwarden/issues/6611 and https://github.com/dani-garcia/vaultwarden/issues/6602#issuecomment-3694436267
