Proxy 12345 May 2026

export HTTP_PROXY="http://proxy.local:12345"

export https_proxy="http://proxy:12345" curl https://api.github.com And you get: curl: (7) Failed to connect to proxy port 12345: Connection refused proxy 12345

Because the hostname proxy doesn't exist, or nothing is listening on port 12345 . export HTTP_PROXY="http://proxy

If you’ve ever dug through a legacy curl command, a Docker environment variable, or a scattered ~/.bashrc file, you’ve probably stumbled across a cryptic string like this: a Docker environment variable

Or maybe you saw the raw log line: "proxy 12345" .

You paste a config into your terminal:

proxy 12345
