zulip-tus returning `http` address when zulip is behind a reverse proxy

[marcustut]

I use the zulip helm chart provided in this repository and I did set

    DISABLE_HTTPS: true
    SETTING_EXTERNAL_HOST: zulip.<redacted>.com

This worked fine, zulip messages and everything are working only when I upload files then it will always fail in the UI

and when I take a look at the browser console:

this happened because of this request to zulip-tus return a http:// url:

Is there a way to configure zulip-tus such that it returns a https:// url?

How is your reverse proxy configured? Is it sending X-Forwarded-Proto headers? Have you configured your Zulip instance to trust your proxy using LOADBALANCER_IPS?

I intend to close this in a week unless we hear more details.
