What’s happening?
Customers are experiencing difficulties logging into the portal, with error messages indicating that access is denied or that the page is not working. This may manifest as the URL switching between the portal and Azure, preventing users from reaching the sign-in page.


Reason:
This may arise due to several factors, including:

  • Misconfiguration of site permissions.
  • Expired authentication keys.
  • Redirect URL mismatches between the portal and Azure AD B2C.
  • Issues with site configuration, certification, CSS/JS code, security, or cache.
  •  
Resolution:
For Login Issues:
  1. Verify that the authentication key is current. If it has expired, renew the authentication key to resolve access issues.
  2. Check the permissions applied to the homepage and ensure they are correctly configured.
For Redirect URL Issues:
  1. Go to the Azure AD B2C application settings.
  2. Under the Reply URL section, ensure that the list includes entries for both the site domain URL and the e-commerce-generated URL. Both URLs must be in a valid format without leading or trailing slashes.
  3. Ensure that the correct endpoint for Azure AD B2C is being used. The deprecated "login.microsoftonline.com" endpoint should be replaced with the appropriate custom domain
