Hi there. This URL should now be working correctly.FWIW, I found the issue why you cannot register with Epic, as there is a typo in the URL that gets generated:
No route found for "GET /epic/register//eyJ0IjoiZXBpY19pZCIsImFsZyI...
This leads to a route not found 404 error. If you remove one of the slashes in the red part, it works, but the JWT token is invalid.
This kind of things happens.I'm glad I didn't spend money on it
