Found source of issue --

Recent changes from regular patching have caused issues with computers with strict NAT types. Tested on 4 different machines on home wifi, home direct connection, and public wifi at a hospital. When on strict NAT type frequent 30605 and 503 errors when performing version check, and if the version check completes 2002 errors upon data center connection. PS4 and other home consoles are notorious for having strict NAT types, especially when on wifi.
