Can we set proxy for dendrite?

[Curious-r]

My server is in a constrained network environment, which is not able to connect to martrix.org. So I set an env:
export ALL_PROXY="socks5://127.0.0.1:2080"
Then I can curl to www.matrix.org smoothly, but my homeserver in this host still can't connect to matrix.org. Therefore I'd like to ask what the correct way to configure a proxy for Dendrite is.
Thanks!

Well, it seems that ALL_PROXY won't work, but HTTP_PROXY HTTPS_PROXY will.

Correct, Dendrite uses ProxyFromEnvironment provided by the standard library.
So you can use HTTP_PROXY, HTTPS_PROXY and NO_PROXY to set the proxy.
