[ask for help] mgrep connection timeout while curl works fine behind a network proxy

[guox18]

Hi, I'm encountering a connection timeout issue with mgrep on a server that uses a unified network proxy.
While standard tools like curl can access external sites (e.g., Google) without issues, mgrep consistently fails with a connection timeout.
