Constant disconnects with no possibility to log back

3 hours ago i started to DC from the server every 5 min. After each DC i have to wait for exactly 10 mins to log back in.

Is it a real disconnect or does the game crash? If you are truely getting disconnected please make sure you are using a clean and none project related 1.12 client. In case the game freezes or is crashing (back to desktop), make sure your add-ons have enough memory to work with. You can increase the value in the add-on selection menu. You can set the value to 512 mb, which should be fine or directly to 0 mb (stands for no limitation).
