I have been Googlin' around forever and can't seem to locate what I need to solve my issue.

Essentially, I have a Core 2.1 Razor web app that is working fine locally, allows users to register/log in with accounts using Identity and view their information.

I published it to Azure, however, the functionality is lost for user registration/login (just times out and/or throws error). I know that I may be needing to use Azure AD, which I have enabled the free trial for.

Could someone give me a high-level view of what I should be doing, or some sources to guide me in the right direction? It's been a steep learning curve trying to put all of this together.
