What do the logs say around the time you tried to save the config?

Either in your data folder as vaultwarden.log, or use docker logs -f vaultwarden or whatever you named your container.

Thanks for the prompt reply! I managed to pinpoint the issue by reading the logs.

@victorshx could you tell us a bit what the issue was?
I would like to see if we can improve upon the error message shown in the web interface.

@BlackDex Firstly, I think the error message in the web interface can be more verbose since logs have already shown which field is missing.

Secondly, failing to send due to TLS enabled will show this error in the web interface.
