I have installed a SSL certificate and when trying to access the site, it asks for a username & password. The http site works perfectly, but the https gives the error?
Regards
Just an update. The error was caused by Microsoft Admin Center. When I uninstalled it, the error went away.
Now I get a "HTTP Error 503. The service is unavailable." - again, only the https gives this error, the http works perfectly.
VERY frustrating. Checked the App pools, deleted the site on IIS and created another one.
Any ideas please?
Solved it - if anyone else has this problem. Some other program (probably Microsoft Admin Center) completely reserved port 443 and was blocking IIS.
