All Servers work apart from 1 and a few others

I can join every server apart from this one server because some dude killed me setting of a trigger not allowing me to go on a server, now everytime I get killed on a server I cant join it, it lets me join but soon as I join it just takes me back to the logging on screen. Its frustrating me and I've tried everything, its my favourite server aswell and if it doesn't work then I might just quit minecraft :/

What I expected to happen was...:
to join a server casually without any crashes (tried joining for like 1 week now)

What actually happened was...:
Everytime I join it goes and logs me out and it wont let me join as it keeps crashing all other servers work (theres not a whitelist because I can go on it on Minechat)

Steps to Reproduce:
1. Joining A Few Servers the main one is mc.moderncraftersdimension.net
2. Getting Killed on any server
3. EVERYTHING!
