This has been happening allot. I will just be playing on my server and "joining world" "The server you were on went down..." I have Tried uninstalling plugins, not building quickly, everything i can think of. If anyone can help I would greatly appreciate it. I really need this server to work. most of my friends live a good distance away and i don't have the money for realms. If this server host dose not work i don't know what to do.
