Hi @kkggboy! I'm Dosu and I’m helping the Stirling-PDF team.

This issue often happens if something goes wrong with the embedded browser (Chromium/CEF) or the local web server during startup. Common causes include missing or corrupt CEF binaries, network proxy issues, or problems with system dependencies like Java. If you’re behind a proxy, try setting Java proxy options as described in this discussion. Also, check the debug.log file in your installation directory for errors, and make sure all dependencies are installed and accessible in your system’s PATH (docs). Restart the app after any changes. If you’re still stuck, let me know your OS, install method (installer, Docker, etc.), and any error logs you see.

To reply, just mention @dosu.
