Troubleshooting

Problem: surge: command not found

• Cause: Surge not installed
• Fix: brew install surge-downloader/tap/surge or go install github.com/surge-downloader/surge@latest

Problem: Connection refused

• Cause: Server not running
• Fix: Start server first: surge server

Problem: Permission denied

• Cause: Output folder not writable
• Fix: Check folder permissions or use -o with writable path

Problem: Download failed

• Cause: URL invalid or network issue
• Fix: Verify URL, check network connectivity

Problem: Too many connections

• Cause: Server limit reached
• Fix: Wait for current downloads or pause some

Self-Check

• [ ] Surge installed: surge --version
• [ ] Output directory exists and is writable
• [ ] For server mode: server is running (surge ls to check)
• [ ] For remote: token and host correct
