Unable to sign in with Microsoft account when connecting to Microsoft Graph for Microsoft 365

[glg9]

I wanted to try Microsoft graph for Microsoft 365 connector. It requires Microsoft 365 login. After selecting the account to log in it shows the following error:

AADSTS900971: No reply address provided. However I have no issues on other sites or services. What can be the reason, and how can we solve?

Thank you!

Configuration of Microsoft Graph is extremely complex and in general not recommended without extensive knowledge of Azure services such as Active Directory and App services.

What is the goal of using Microsoft Graph?
