Everytime I try to connect to my own server on lemehost, I get a warning saying that the server is still starting despite the server status reporting as running. I'm not running any mods, and no authkey. The server has worked beforehand approx. 1 year ago (even with mods), and this is not related to the recent security breach, as it still didn't work beforehand.
Any ideas, anyone?

Try to reinstall the server

Just click Reinstall in the settings tab
