About ServerWatch — Connection Diagnostics

Find out why a website is blocked or not loading — instantly. ServerWatch is a network diagnostics extension that tells you the exact reason a site is unreachable: ISP or DPI block, DNS blocking, local firewall, VPN issue, SSL certificate error, or real server downtime. WHY IS THIS WEBSITE BLOCKED? If a site won't load, ServerWatch runs a full diagnostic and gives you a precise answer: • Is the site blocked by your ISP or DPI filter? ServerWatch detects when your connection is cut while the site is globally reachable. • Is it a DNS block? Checked via DoH (Cloudflare / Google), independent of your local DNS settings. • Is the site actually down? Cross-verified from external servers worldwide via check-host.net. • Is it your VPN or proxy? Detected and explained clearly. • Is it a firewall or antivirus on your device? Identified as a local block, not a network issue. • Is it an SSL certificate problem? Exact error shown (expired, untrusted, wrong domain). WHAT SERVERWATCH DETECTS ✓ Site is available — connection and HTTP response confirmed ✗ ISP / DPI block — site is globally reachable but blocked in your network ✗ DNS blocking — domain resolves publicly but fails in your connection ✗ Server down — unreachable locally and externally (real outage) ⚠ SSL certificate error — expired, invalid, or untrusted certificate ⚠ Blocked by antivirus or browser extension — local device block ⚠ Bot protection (403/429) — site is up but blocking automated requests ⚠ Port blocked by ISP — port open externally, blocked in your network ✗ Domain not found — unregistered or misconfigured domain SERVER MONITORING Add servers and ports to monitor in the background. Get a desktop notification the moment a status changes. Configurable check interval (1–60 minutes).
