Hey,
since today, after the wipe, I can't join my server anymore. Whenever I try, this error message shows up:



I didn't change, add or remove any plugins, I just changed the world to Hapis Island (it was a procedual map before).
Does anyone has an idea what could cause that issue?

EDIT:
Also the current map displayed is "Bootstrap", dispite the fact I selected Hapis Island.

This seems to be why, you should change the map on the server. Hapis was removed 6. May.

Alright, I did not know that...
So I changed the map back to procedual - but now I get different errors. The last one is gone but when I try to join, it takes me back to the main menu, showing me this



The red text appears in the top left corner, the white text under the server information.
