I ran into the same problem. After above fix changing the URL fixed the original issue, I am getting an error with token response response at line 75 of https://github.com/oktadeveloper/okta-aspnet-mvc-example/blob/master/OktaAspNetExample/Startup.cs. Error is “not found”.

            AuthorizationCodeReceived = async context =>
            {
                // Exchange code for access and ID tokens
                var tokenClient = new TokenClient(
                    issuer + "/v1/token", clientId, clientSecret);
                var tokenResponse = await tokenClient.RequestAuthorizationCodeAsync(context.ProtocolMessage.Code, redirectUri);

                if (tokenResponse.IsError)    // <---- error occurs here with "not found"
                {
                    throw new Exception(tokenResponse.Error);
                }

issuer is “https://{{myOktaTrialPrefix}}.okta.com/”
