    If you are experiencing issues signing into the Microsoft Authenticator app and encountering an HTTP Error 500.30 when trying to access your account on a computer, here are some steps you can take to troubleshoot the problems:

    1. Authenticator App Issues:
      • Ensure that you have the latest version of the Microsoft Authenticator app installed on your mobile device. An outdated version can cause sign-in issues.
      • If the app is updated and still not working, try uninstalling and reinstalling the Microsoft Authenticator app. Make sure to back up your accounts before uninstalling.
      • Check if there are any third-party security apps on your device that might be blocking the Authenticator app from functioning properly.
    2. HTTP Error 500.30:
      • This error typically indicates that the ASP.NET Core application failed to start. It could be due to various reasons such as configuration issues or missing dependencies.
      • Ensure that your account is properly configured and that you have the necessary licenses assigned. If you suspect that your subscription may have been compromised, it’s advisable to contact Microsoft support directly for assistance.
      • You can also try accessing your account from a different browser or clearing your browser's cache and cookies before attempting to log in again.

    If these steps do not resolve your issues, consider reaching out to Microsoft support for further assistance, especially if you believe your account may have been compromised.

    Hi, it sounds like you're dealing with both a sign in loop on the Authenticator app and a server error when accessing your account. First, make sure the app is updated or reinstall it after backing up.

    Also, check if any security apps might be interfering. For the HTTP 500.30 error, it could be a misconfiguration or missing dependency, try a different browser and clear cache.

    If you think your account was hacked, it's best to contact Microsoft support directly. here's the link, https://support.microsoft.com/en-us/topic/customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

    Also, when did the issue with the Authenticator app and the HTTP error start, was it after a recent update or change to your device or account?

    I hope this helps you, let me know how it goes.
