Captain, in the report you have recently sent there is a problem with connection (incoming packets) - most likely the issue is about firewall blocking certain ports
The list of required ports is:
7770, 8089, 5672, 5222, 8080, 21020-21036, 7401-7600 (highlighted ports are ports needed for battles)
Also, do you have an option to temporary test the game via a different source of internet, e.g. mobile connection?
