Update jsmon.py

[lupedsagaces]

📋 Problem Description During production usage, I identified scenarios where JSMon can fail or behave unstably:

Missing files: Script crashes if files in downloads/ directory are removed Network failures: No automatic retry for temporary connection issues SSL certificates: Expired/invalid certificates cause crashes Bot detection: Basic headers may be blocked by anti-scraping systems No timeouts: Requests can hang indefinitely

✅ Benefits Zero breaking changes - maintains full backward compatibility Higher reliability - works even with connectivity issues Automatic recovery - continues working after downloads folder cleanup Reduced blocking - realistic headers avoid bot detection Modern Python - f-strings and best practices Better logging - clearer error messages Graceful degradation - continues monitoring even when individual endpoints fail

🧪 Testing I have implemented and tested these improvements in a production environment where they successfully resolved:

Intermittent network connectivity issues SSL certificate problems with some monitored endpoints Accidental deletion of historical files Detection and blocking by Cloudflare and similar services

🎯 Implementation I have a complete, tested version ready. I can create a Pull Request if there's interest. All improvements maintain 100% compatibility with existing configurations and workflows.
