Always get Disconnected when attacking in War

It’s very frustrating that I always get disconnected when attacking in Clan War even with stable wifi connection. Please don’t tell me not to use bots, ♥♥♥♥s or any form of ♥♥♥♥♥, because I don’t. I play fair.

I already got disconnected THREE times and my clan suffered great loses because of this. I never get disconnected when looting. This disconnection problem only happens when I am attacking in war. I get disconnected even before deploying my first troop. I tried to use my clan mate’s account in my device with the same wifi connection to attack in war and he did not get disconnected.

Has anybody encountered this problem? I really need to fix this.
