Hi @rkrenn
Welcome to the Auth0 Community!
Looking at the URL provided, I would say that it’s generally in order, but allow me to show an example of how the login_hint needs to look when passed in the URL :
https://[Tenant].auth0.com/authorize?client_id=[Client ID]&response_type=token%20id_token&redirect_uri=https://jwt.io&scope=openid&login_hint=user1@gmail.com&state=1234&nonce=5678```
Depending on the error message or exact issue that you are facing, it could also be that the state param is not being passed correctly, just making sure in regards to the example that you provided.
More information can be found in the following posts made on this topic, which I encourage you to take a look, at your convenience :

Hope this helped!
