SSL error - login through Xamarin Forms Android app, citing OpenId error

Hello,

I’ve had this working for a while, no code change.
Updated Xamarin Form Android app to use Xamarin.AndroidX plugins and libraries.

I’m now get a failure on this call:
var auth0LoginResult = await _auth0Client.LoginAsync();

Is there an SSL requirement now when setting up the Auth0Client?

Any advice? I’m obviously missing something but unsure if this is a Auth0 error and I need to do something THIS side or fix something in the login code in my app.

Implemented this Auth0 Xamarin SDK Quickstarts: Login quite a while ago, been working just fine up to now…

Does the error mean I should now be using OpenId?
Does await _auth0Client.LoginAsync(); now use OpenId?

I have not specified OpenID in my Auth0 settings or in the app itself…

This is this SSL error (innerhtml):
