I already tried deleting Battle.net Cache, Battle.net folder from ProgramData
Secondary Logon already set to automatic
Run as Admin from Launcher (also tried run admin from diablo3.exe itself)
Still the same.. worst part is when i launch again after waiting for a few minutes
the agent.exe multiplies in task manager
I did "fix" it once by reinstalling the game which is a pain in the a** but after that it worked...
and issue happened again same scenario with all the applied fix =)
