Ip changed overnight, now server doesn't work

I changed all of the settings accordingly, as usual, re-opened my ports etc

then this shit

help.

That error shouldn't be due to an IP change but if it is the case, just use NoIP and have the server connect to the custom generated IP.

If you still get an error, then you will know it isn't that

Try to go to the server/wserver.cfg in the actual bin folder and open them both and look for errors, sometimes it prints "e" into the bottom of the config files :L?
