OAuth reporting bad redirect uri but only after redirect

I have a blazor app with OAuth through Discord and Google. I have this working locally fine, and I'm trying to move this to a server to deploy it. Problem is, I'm getting an error when Google/Discord redirects me back to my site. On the browser, I just see a 500 error, and in my logs I get this:

fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HN4BDNS95F1R", Request id "0HN4BDNS95F1R:00000001": An unhandled exception was thrown by the application.
      Microsoft.AspNetCore.Authentication.AuthenticationFailureException: An error was encountered while handling the remote login.
       ---> Microsoft.AspNetCore.Authentication.AuthenticationFailureException: OAuth token endpoint failure: redirect_uri_mismatch;Description=Bad Request
         --- End of inner exception stack trace ---
         at Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler`1.HandleRequestAsync()
         at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context)
         at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.ProcessRequests[TContext](IHttpApplication`1 application)

This looks a lot like what you'd expect to get if your redirect url wasn't specified right in the configurations for each site, but I've checked very carefully. Also, when I previously hadn't put in the url yet, it was stopping me before I could even try to sign in. Does anyone know what I'm missing here?

Getting the Value of XElement including tags

I have an XElement and I want to get its value, including any child elements of it expressed as tags. So for example, I have

<test>1<a>2</a>3</test>

<test>1<a>2</a>3</test>

And I want to get 1<a>2</a>3 as a string. What's an easy way to do that?
