Using the link from the Battle.net launcher (windows pc), it took me to ‘oauth,battle,net/authorize’ which was reported as an insecure connection.
(can’t post with links, so I changed the periods to commas)
So I closed it and used the launchers link again. Insecure again… This time I clicked through to see where it took me, but in no way was going to enter any information if it asked for it.
It loaded ‘Aquent CloudWall’ with only a checkmark to enable cookies and a grayed out button to login with google.
Insecure connection to an unknown site, wanting to add cookies, and seemingly asking for a google login… nope! all too sketchy for me. (I just used the android app instead)
I don’t know what was going on but figured it was best to report here just in case there is an issue. To add to the weirdness, I used the launchers link again to get the URL for this report, and it just worked normally.
