How to connect? Azure Service Connection Authentication in Azure DevOps– Stuck on Blank Callback Page

Question

I am trying to create a Service Connection in Azure DevOps using Docker Registry and Azure Resource Manager. After selecting my subscription and completing the 2FA authentication, I get redirected to a link ending with ***/completecallbackbyauthcode, but instead of proceeding, I see a blank white screen.

I have attempted different approaches, including using different browsers and clearing cache, but the issue persists.

After restarting my machine, the issue changed to a 404 error, and I am still unable to add the Service Connection.

Due to this issue, I cannot deploy my three projects, and I am also encountering errors when configuring a job in the release pipeline.

Please provide guidance on resolving this issue.
