Use the Salesforce CLI from Behind a Company Firewall or Web Proxy

You get an error similar to the following when you run a command after installing the CLI binary behind a firewall or web proxy. This error is from a Linux computer, but Windows and macOS users sometimes see a similar error.

1sfdx-cli: Updating CLI... !
2 ▸  'ECONNRESET': tunneling socket could not be established, cause=connect EHOSTUNREACH 0.0.23.221:8080 - Local (10.126.148.39:53107)

To address this issue, run these commands from your terminal or Windows command prompt, replacing username:pwd with your web proxy username and password. If your proxy doesn’t require these values, omit them. Also replace proxy.company.com:8080 with the URL and port of your company proxy.

1npm config set https-proxy https://username:pwd@proxy.company.com:8080
2npm config set proxy https://username:pwd@proxy.company.com:8080

Then set the HTTP_PROXY or HTTPS_PROXY environment variable to the full URL of the proxy. For example, on UNIX:

1export HTTP_PROXY=https://username:pwd@proxy.company.com:8080

1export HTTPS_PROXY=https://username:pwd@proxy.company.com:8080

1set HTTP_PROXY=https://username:pwd@proxy.company.com:8080

1set HTTPS_PROXY=https://username:pwd@proxy.company.com:8080
