Cannot select Java servers

I set up my server, download Java server on MineOS UI, open a server for testing, close it, set up a static IP, now I cannot select Java servers.

I literally have no idea what happened, I tried searching it up but I saw no results.
BTW I am using Ubuntu Server.

Also the commit of the site is 2ef3e17

Any interesting entries in /var/log/mineos.log?

Did you restart the webui after setting a static IP? (e.g., is the old process still listening to a previous ip?)
