I'm using Blazor Server side and Auth0 to deal with logins to my app.
I get to the login screen fine but when I click OK to login with correct credentials I get this:
Exception: OpenIdConnectAuthenticationHandler: message.State is null or empty.
Exception: An error was encountered while handling the remote login.
Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler<TOptions>.HandleRequestAsync()
Works fine localhost but not when running in my Beanstalk AWS environment.
I have added all relevant callback URL's inside Auth0 dashboard.
My Startup.cs has this for the callback which I believe shouldn't be an issue.
// Set the callback path, so Auth0 will call back to http://localhost:3000/callback
// Also ensure that you have added the URL as an Allowed Callback URL in your Auth0 dashboard
options.CallbackPath = new PathString("/callback");
