Run VS Code behind a proxy with HTTPS_PROXY set to an http url 2. Use the Atlascode or any extension that makes https calls Expected: the requests work Actual: the requests fail. Most of the time the error reported is "socket hang up" I believe the chromium proxy stuff internally handles tunneling https to http when running behind an http proxy, However, I don't think VS Code handles this when it rewrites the https module for extension proxy support. We've been able to get around this by adding this to our axios requests when behind a proxy: ``` const [host, port] = getProxyHostAndPort(); let numPort = undefined; if (host.trim() !== '') { if (port.trim() !== '') { numPort = parseInt(port); } agent = { httpsAgent: tunnel.httpsOverHttp({ proxy: { host: host, port: numPort } }), proxy: false }; } ``` It would be ideal if VS Code just handled this for extensions.
