Enterprise Connection config issue


I’m sort of new to Auth0 and we are trying to create a POC for management. Part of the requirement involves integrating Auth0 with our company’s identity server built using openid/oauth protocol.

We are running into issues creating enterprise connections, specifically setting the issue url to the identity server application deployed in one of our test environments which is not accessible on the internet. However, we can successfully point it to the same application on our prod environment which is accessible on the internet.

Now with the context in mind, is this achievable (pointing the issue url to our test environment)? If not what’s the appropriate way to do this? I am currently on my company’s VPN so I sort of assumed auth0 should be able to reach the endpoint.

Any help would be indeed appreciated. Thanks
