ERROR APPLYING UPDATE - UNKNOWN ERROR (0)

[MTT86]

Has anyone else encountered this issue since the 7/9 update launched? I've updated my computer, shut down and reopened the app, deleted and reinstalled it- all to no results. Wifi is fine, never had any issues before and can run other online games without issue. For some reason I can't join an ow game at all- vs ai, missions, qp or comp. Any results on the blizzard support link haven't worked, I justt have a yellow warning icon in all of my online game options on the main menus. Does anyone know what I could do?

I've seen this only once, and that was prior to this update. For me, just closing down the game and running it again a little while later was enough to get things back in order again.

Based on the error code, I can only assume there was a fault in packet processing during launch. That can likely be due to a poor connection or some problems with your modem/router/ISP (basically, anything in the chain between your computer and the game's servers).

Just let the game sit for a while and try it again later.
