Error: BLZOWCLI00000004


I am receiving this code and game is crashing to desktop (PC). All my drivers are up-to-date. I have reinstalled Windows, drivers and game couple of times with clean installs. I have verified game and windows files.

We have exhausted every option on Blizzard support (on ticket) and NVIDIA support (on live chat). That includes OverwatchTest.exe (which sees as a problem and verifies game with creating an exe without “Test” ) as well.

My graphics card is 4070 ti by the way. I used to play the game but I haven’t been able to for a couple of months. I tried my luck when I had a clean format on my PC but still stuck there.

Do you have any solutions?

Seems like is a CPU issue… Solution on Reddit.
