Error AADB2C90205

Hello

We have a multi-tenant application of type SPA in React calling Web Api in .Net and uses Azure B2C and MSAL libraries for authentication.

We need to give customers the possibility to create their own tenant from the client app based on the subdomain they want.

To set up a new tenant, we create an app registration for the subdomain via api graph.

Unfortunately after creating the app registration we have to wait about 30 minutes before we can sign-in, in the meantime we always receive an error AADB2C90205.

In my case it is essential to give customers the opportunity to authenticate in the app with a sub-domain quickly.

Can you show us a way to solve this?

Hi @Egidio Torresi , thanks for your post! I'm looking into your question but this error typically occurs when using the refresh token to get a new access token for a different scope.

Hi @Marilee Turscak-MSFT
OK, I can verify this, but it seems strange to me that trying again after enough time has elapsed the authentication is successful.

I look forward to any further feedback from you....

Thank you very much!
