I created one website on Firebase, now I want to move the website out from firebase. On the new hosting server, the website url keeps visiting 443 port.
How can I force
Firebase Hosting will only serve traffic over HTTPS, so port 443.
There is no way to force traffic to be served over non-secured HTTP. But traffic coming in to port 80 will (or at least should) automatically get redirected to port 443 with a 307 response.
From a quick test request I just did:
Request URL:http://trenches.firebaseapp.com/
Request Method:GET
Response
Status Code:307 Internal Redirect
Location:https://trenches.firebaseapp.com/
Non-Authoritative-Reason:HSTS
