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 the port change? Is there any cached on the web browser I need clean them up maybe? I want to make it 80 port by default.
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/
