Answer 1

FindUserFromExternalProviderAsync should be a method in ExternalController -- the errors are complaining that it's missing in your copy.

Here it is: https://github.com/IdentityServer/IdentityServer4.Quickstart.UI.AspNetIdentity/blob/main/Quickstart/Account/ExternalController.cs

Answer 2

Nvm solved it. the original method wasn't Async.
