An Azure managed MySQL database service for app development and deployment.
Hi Stefania,
Since the individual Entra administrator is working, I would first recheck the user-assigned managed identity configured for the MySQL Flexible Server.
For group-based Entra administration, Microsoft documents that the managed identity requires User.Read.All, GroupMember.Read.All, and Application.Read.All permissions. Alternatively, the managed identity can have the Directory Readers role. Microsoft also supports selecting an Entra group as the administrator.
If these permissions are already configured correctly and the same InternalServerError continues from both the portal and CLI, collect the failed operation/correlation details and open an Azure support request for further investigation.
