Can't grant permission to access graph API due to a transient error

Hello all,

I tried to give permissions to another tenant in order to access some resources via graph API.

I went to the following URL for 'admin_consent' to grant permissions, but it failed due to a transient error 

    https://login.microsoftonline.com/common/oauth2/authorize?redirect_uri={encoded redirect uri}&response_type=code&client_id={client_id}&prompt=admin_consent

The endpoint returned a response, which said:

    AADSTS90090: A transient error has occurred. Please try again.

Additional Information:

Permissions I want to grant are:

• Read directory data
• Read and write directory data
• Enable sign-on and read users' profiles
• Access your organization's directory  
  

I'd appreciate any help.

Thanks
