Server Log ^

We no longer support any minecraft version older than 1.16 at this point.

Should you be able to confirm that this issue still applies to the most recent version, please update the issue and we will reopen it.

[20:38:39] [Server thread/WARN] [net.minecraft.server.dedicated.DedicatedServer]: **** FAILED TO BIND TO PORT!
[20:38:39] [Server thread/WARN] [net.minecraft.server.dedicated.DedicatedServer]: The exception was: java.net.BindException: Cannot assign requested address: bind
[20:38:39] [Server thread/WARN] [net.minecraft.server.dedicated.DedicatedServer]: Perhaps a server is already running on that port?

@yueh any idea why there is a AE2-Core NullPointer Crash at the end of that log after the server failed to bind the port? (just out of curiousity)
