Whenever I attempt to log into battle net on my WiFi it will not let me. It gives me the error code above on the desktop app and a 403 forbidden code in google. Battle.net is the only one that gives me problems. I can disconnect from my WiFi on my phone and with my data log into battle.net. I have already tried every step that blizzard support has provided including contacting my internet provider with no results from them.
Checked firewall and proxy
Undownloaded and redownloaded the desktop
Restarted WiFi
DNS flush
Released and renew ipconfig
And whatever other steps blizzard tells you.
