I downloaded Battle net setup EXE just now from the main website - and when I check its certificate in WIndows - it shows that certificate is valid only until 30/11/2023
I am pretty sure this is the reason I am struggling with this Blzbntbgs80000011 error. I started having it approximately around this date. Half a year ago I managed to make it working, but recently it all reset again and I am again stuck at this error.
I tried every existing remediation manual. I am on freshly installed clean system. Firewall off, defender off. New admin account doesnt’t help. Reseting network, flushing etc - all doesn’t help. Another network - doesn’t help. Another account - doesn’t help.
This got to be the reason behind this stupid error. Weird part is that it doesn’t allow me to login to bnet account - but it can download games and show news just fine. I can login in my web browser just fine, as well. So this got to be some issue with the authentication inside battle-net application itself - and expired certificate on the installation binary seems like very plausible explanation.
