Remote docker server error

Hello, I have came across docker deployment issue on a remote server. I’ve tried using Hetzner and everything is working fine, however, once tried set up with the Ionos, I have successfully connected to the remote docker engine, but unsuccessfully save “target settings” changes. I am wondering whether there’s docker miss-configuration on the server side, or there’s further setup steps needed.

Seems there are some UI errors when using directly the freshly created docker server.

Maybe just cancel and reopen the settings, select the docker server in the target and save.
