Warning Code 80 error weird

Warning Code 80 error I received after completing GR 75 with my Barb just checking to see if it is code related to the new patch or something. Thank You

You sure it wasn’t code 30? That is what I got and reports of lots of others getting it too.

I’m getting error code 30, too. Started out as a game freeze right as my character logs in, so I followed another post where a Blizz tech said to reset game settings. Did that, no more freezing but now I get this error code 30. /sigh

it did say error code 80 and just now while playing in the normal rift I just received Warning Code 30 Error I think there is something wrong with patch 2.6.6 please look into it Blizzard Tech Support
