Remote connection to machine with HTTP proxy with zed fails

[saidelike]

Reproduction steps

At the moment, we can't use zed properly with a remote server that requires a proxy. This is typically the case in an Enterprise/Corporate environment.

I posted this in discussion (#43405) initially but I guess it is better here hence reposting.

Current vs. Expected behavior

I've tried different things:

1. starting zed on my host from a shell with defined proxy (in http_proxy, https_proxy and no_proxy environment variables)
2. configuring the proxy in my host Settings file ( { "proxy": "http://..." })
3. configuring environment variables in the project Settings file ( { "env": {"http_proxy": "...", "https_proxy": "...", "no_proxy": "..." } or the same under {"terminal": {"env": {...}})

For 1., 2. and 3., proxy is not inherited by the remote connection. For instance, it fails to download node, codex-acp, etc.

2025-11-24T14:26:43+00:00 ERROR [remote::remote_client] (remote server) server:error handling message. type:GetAgentServerCommand, error:fetching Codex latest release: error fetching latest release: error sending request for url (https://api.github.com/repos/zed-industries/codex-acp/releases): client error (Connect): operation timed out

4. configuring environment variables in the remote server's .bashrc.

For 4., I get an error when zed attempts to connect to the remote server:

As you can see in the logs, my .bashrc is showing the environment variables (e.g. env|grep -i proxy in the `.bashrc), so I know they are loaded.

Looking for "proxy" in https://github.com/zed-industries/zed/blob/3281b9077fddb7d40278c0479b27e1fb5f2c9c0f/docs/src/remote-development.md does not give anything useful.

Any update on this? This is preventing me from being able to use Zed, unfortunately.

Proxy stuff definitely still doesn't work right. Just installed the latest Preview release and now I'm getting errors that I wasn't before. I had my proxy defined in my settings file but only some things would work unless I put my credentials in the proxy URI. Now I get an error when trying to connect to my WSL remote that the operation timed out when trying to download the remote server.

thanks for reporting. we're looking into a few issues with remote right now, something definitely seems to be off
