Dynamics 365 Plugin Registration Tool gives permission error

When I try to connect to Dynamics 365 CRM with the Plugin Registration Tool I get the following permission error:

"You don't have permission to access any of the organizations in the Microsoft Common Data Service region that you specified. If you're not sure which region your organization resides in, choose "Don't know" for the CDS region and try again. Otherwise check with your CDS administrator. Parameter name: EMEA"

  • I have the System Administrator role
  • I can sign-in to the web interface and work with no issues
  • I'm sure of our region, tried to login with and without it ("Don't know" option)
  • Also tried with an application password as our organization uses multi factor authentication
  • Using the latest version of the tool on Nuget (9.0.0.9506 in the about dialog)
  • I can connect to my trial server the same way
  • We had a user who was able to connect with the same user roles set
  • This seems machine and account independent. Other users including the organization creator are getting the same error
  • We are directly connected to the internet, no proxies
  • One solution I've read suggested cleaning the cache files which don't appear on my system. And we get the same error on clean installations.
Solution

  • Solved by leaving the "Show Advanced" checkbox unchecked and not entering User ID / Password. Then a second dialog opens for credentials and 2FA authentication which just works.

    You don't need an application password, as you'll be asked for MFA in the next step.

    I don't know how our old teammate was able to sign in with the "Show Advanced" option selected. He was getting the same dialog and continue.
