I just started my server last night with a lot of plugins installed with it. I had 2 people joined that are good friends. It was still working as usually and there was no lag at all. After a while I just turned off the server and went to bed. I woke up and started up my server.bat and typed in my IP on Minecraft and it wouldn't connect. It so many times before I don't know what happened. I deleted some plugins and it still wouldn't connect. Can you help with this problem?
