Guild war is not working properly

Hello, please can you help me with my problem? I attacked on GW, but it kicked me from the server and the moment I'm "supposedly" able to reconnect, it sends me a message saying the battle is over, and when I look at my "attack" it doesn't show that I attacked..... Please, can you give me back my "entry ticket" so I can attack? (I put the 2 images) ((I translated this text with Google Translate, sorry)) PLS HELP ME
