The issue I am facing:
I play Call of Duty, Modern Warfare 2. Recently I noticed I was not able to login to the battle.net Windows app and kept giving me an error... "BLZBNTBNA00000005 (Battle.net Agent Went to Sleep"
I tried many things and nothing worked. I have been using 1.1.1.3 - 1.0.0.3 as the upstream server which is Clouflare's family, which blocks porn and malware. I tried changing the upstream dns server to 1.1.1.2 - 1.0.0.2 and the issue went away.
I guess the 1.1.1.3 - 1.0.0.3 DNS now doesn't like battle.net. Is there a way for me via Pihole, bypass or whitelist the server IP. (don't know which one it is). I would like to keep using 1.1.1.3 - 1.0.0.3.
If replace <DOMAIN_NAME> above with the domain that needs to be forwarded to those less restrictive DNS servers (1.1.1.2 & 1.0.0.2), this will do the trick and it will also cover any sub domains.
But you'll have to figure out which domain (or more) exactly.
Below tools might help with that:
