Im trying to run a server with my friends to play skyfactory 1 (the one that runs in 1.16.5) and im getting an error in the console when i run the server.  

full console looks like this.

I already switched my java version, as another post on this forum suggested I do.

the only difference between mine and that post was some numbers and the line that I put in red (second from the top).
