Server Crashes On Startup

Hi, Every time I launch my server it crashes. It runs and then just shuts down. It worked like 2 hours ago when me and my friend were playing. They’re no mods on the server currently so idk whats happening. Please Help

if you didn’t change anything in the 2 hours, just remove the cashe

What is the cache?

Also, it worked thanks. But it doesnt show my server in the server list. And I try connecting through the IP and it doesnt work

Anything in the server log? Is it hosted on your PC?

@WolvesRoot did you port forward it?
