Hi @kurt-shipad , not sure about your situation. I have a hunch it’s probably mostly related to the IIS and proxy settings. Also you might want to check your DNS registrar.
In my situation with Heroku, they will give you a unique subdomain like *.herokudns.com to create a CNAME record for. You will also want to make sure you are using SSL on your hosting platform, so either you need to configure your own cert or they will do it for you.
Then, like mentioned above, make sure you create environment variables on the hosting platform to match your .env for local dev.
Beyond that, I’m afraid I’m not much help b/c it’s probably an IIS thing.
Hope that helps somewhat. Good luck!
