Minecraft crashes when joinen on Nitrado server always off?

If I want to join my Nitrado server, my Minecraft always crashes directly. The first 10 days everything worked perfectly. The server runs with the modpack "The 1.7.10 Pack". The first time the game crashed when I put a cable from Mekanism (the days before I could easily) and since then the game always crashes after about 1 second after the joinen.

In the console it says:

[14:14:20] [Server thread / INFO]: burprinz joined the game

[14:14:46] [Server thread / INFO]: burprinz left the game

If it has stopped running since being placed, the crash is due to the cable. Backup play from before the cable was placed then it should run again.

I only find a backup of 13:00 and 14:00, but I have the problem since about 11:00. Has the backup been deleted?

I can't tell you that.
