Run remote cursor server with proxy

Discussions
1

I use Cursor with project on a remote instance. Cursor can ssh and copy server there, but the server can’t index project, because access to https://repo42.cursor.sh available only via Proxy.
Is there a way to configure only server to use Proxy?

Edit: I did try to set http.proxy in remote settings.json - didn’t help
Edit 2: setting proxy vars in /etc/environment didn’t help as well
Edit 3: I was able to index the project, editing ~/.cursor-server/bin/9f33c2e793460d00cf95c06d957e1d1b8135fad0/bin/cursor-server

HTTPS_PROXY=http://myproxy HTTP_PROXY=http://myproxy https_proxy=http://myproxy http_proxy=http://myproxy "$ROOT/node" ${INSPECT:-} "$ROOT/out/server-main.js" "$@"

But now I’m looking for a proper way to do it

Hi @Gennadiy_Kartashevsk, apologies for the delay here. When using a remote SSH server, we support configuring a proxy via the remote.SSH.httpProxy and remote.SSH.httpsProxy settings.

Hey! Thanks, but see my original message, you’re referring to I did try to set http.proxy in remote settings.json - didn’t help If I set remote.SSH.http(s)Proxy in local settings - I can’t even ssh, because proxy is not available from local machine

Hi @Gennadiy_Kartashevsk,

You can set these settings from a local cursor window. They are stored client side, not on the remote machine.

Thanks, but with these settings in local I can’t even ssh

Could you share the full logs from the “Remote - SSH” output console? These proxy settings (remote.SSH.*) would be applied after the SSH connection itself is established (but before the remtoe server is downloaded). They wouldn’t affect establishing the remote connection.

@ravirahman any updates? It’s very frustrating to setup cursor server when you need to manually edit remote files

13

These error indicate that the proxy was not reachable from the remote machine. Could you double check that the proxy url is correct?

14

Yes, proxy is correct. Also, without proxy setting it at least fallbacks to scp, but not with proxy settings
