SMTP with OAuth Authorization Error

[datafastlr]

We have sites running DNN 9.13.8 using OAuth in the SMTP Authentication. They work fine.

We recently set up a site using DNN 10.1.2, however when authorizing we get error AADSTS50011, even though the settings on Exchange and DNN are configured correctly.

On the error, we noticed that the Redirect URI has HTTP and not HTTPS (see attached image), even though the SSL is forced through the whole site. Not sure if that is the problem or if it is something else. Any help is appreciated.

Regards,
Larry

Disregard... we had "www" on our Redirect URI. Once we removed it, the authorization worked. I do stupid things sometimes...lol.
