Using HTTPS between proxys

I would like the requests to be sent encrypted over the internet. Sure, i can just use the https url, but that only works up to the first proxy, which forwards the request over plain http. Is there any way to do that?

The requests are encrypted on the internet. The rest of the pathway isn’t on the internet, it’s between machines in AWS.

Does that solve your problem? What’s the threat model that you’re concerned about?
