Can someone please help me?!?!

 

I don't see a server running anywhere :/

 

Restarted my whole PC. Didn't worked.

 

Did you leave the server-ip= blank in the server.properties? If not, do that and try again.

 

Worked.
It's weird because yesterday it just worked and I had also some things behind server-ip...

Anyway it worked. Thanks!

 

Yeah, just always leave it blank, your computer will automatically pick the correct address to use. Your ipv4 address probably changed, which caused the one in the server-ip= location not to work.
