I recently ran into an issue after a laptop restart. My Chrome was upgraded to version 81.
In this version, by default, if you run a website in Incognito mode; it does not send your credentials to the server. It keeps prompting for a username/password while connecting to a http authentication sites.
Path in regedit: Computer\HKEY_CURRENT_USER\Software\Policies\Google\Chrome
Create a Registry Key: AmbientAuthenticationInPrivateModesEnabled with value “3”
0 = Enable ambient authentication in regular sessions only.
1 = Enable ambient authentication in incognito and regular sessions.
2 = Enable ambient authentication in guest and regular sessions.
3 = Enable ambient authentication in regular, incognito and guest sessions.
