SonarQube 9.4 and SAML Login issue

We have just installed SonarQube 9.4 on our brand new Windows Server 2019 machine. The installation/configuration went well, however, we are not able to logon SonarQube using SAML due the error below. We have tried whatever we can to replicate a working environment (SonarQube 7.9) to this new machine, but none of these works yet. Very appreciate if you can give us some insights on what may have been missing to correct so we can move forward.

Error: You’re not authorized to access this page. Please contact the Administrator. Reason: The response was received at http://.com/oauth2/callback/saml instead of https://.com/oauth2/callback/saml*

Hi,

There are lots of topics that cite this error string. Here’s a good one:

 
HTH,

We have tried this article by adding Reverse Proxy rules in web.config but it doesn’t change. Still getting the same error message.

Hi,

Sorry, but I just don’t have the expertise to go further with this.
