Solved Can´t connect to FTB Infinity 1.10.1 Server

Me and my freinds are currently having problems in connecting to our Minecraft Server.
While my client closes immediatly once I tried to connect to our server, my friends are able to connect, but after about 10-20sec. their client crashes also.
Here´s a picture of the console, it shows the reaction of the server, if someone tries to connect:

I would appreciate it if you can help me and my freinds, if there are any questions, feel free to ask.
