request scheme reports http when requested over https

[joymittens]

Hello community, I'm new to this forum so forgive me if I don't know the correct etiquette.

I'm having a very odd issue.

I'm migrating from google app engine to cloud run using the automatic build pack for Python3.10

My app uses Flask and whenever I query `request.scheme` or `request.host_url` etc I get 'http' even when I explicitly request a https route from the browser and there is a reassuring lock icon confirming it is all over https. (This was not happening in the app engine.)

Anyone have any idea why my request might be getting downgraded to http or why the request object would be incorrect?

Any help would be greatly appreciated.

Hi @joymittens,

Welcome to the Google Cloud Community!

You can try the following troubleshooting options:

1. You should look into the documentation, Invoking with an HTTPS Request. You can send HTTPS requests to trigger any Cloud Run services. 
2. Set up an HTTP-to-HTTPS Redirect for a Classic Application Load Balancer. You have to set up a load balancer using the Google Cloud Console. This will then direct all your requests from HTTP to HTTPS.
3. Check this blog out to learn more about Google Cloud Run - HTTPS
4. You can also get in touch with Google Cloud Support if the above options don't work.

Let me know if it helped, thanks!
