What does Lemwatch monitor?

Lemwatch runs 20+ automated checks per site: uptime, response time, SSL/TLS expiry, domain expiry, DNS changes, sitemap health, broken links, content changes, SEO audits, mobile usability, security headers, and more.

Yes. The free tier monitors up to 5 sites. Pro is $19/month for 50 sites and Agency is $59/month for 100 sites, both with full feature access.

How is Lemwatch different from UptimeRobot or Pingdom?

Lemwatch bundles uptime, change detection, SEO audits, security scans, and a public API in one platform — features competitors charge separately for. It also includes team workspaces, white-labelled status pages, and a webhook system out of the box.

Does Lemwatch send alerts?

Yes. Lemwatch supports email, browser push, webhooks, and per-site notification routing so the right person hears about the right incident.

Is there a public API?

Yes. Pro and Agency plans get a public REST API with webhooks for sites, checks, incidents, and reports.

HTTP 522 Connection Timed Out

Cloudflare could not negotiate a TCP handshake with the origin server.

What 522 means

HTTP 522 is a Cloudflare-specific error indicating that the TCP connection to the origin server timed out. Cloudflare tried to connect but the origin didn't respond within 15 seconds.

Common causes

Origin server is overloaded
Network issues between Cloudflare and origin
Firewall rate-limiting Cloudflare requests
Origin server has keepalive disabled

How to fix it

Check origin server resource usage
Enable TCP keepalive on origin
Whitelist all Cloudflare IP ranges
Check for network routing issues

SEO impact

Site appears down to all visitors and crawlers. Extended 522s will hurt rankings.

Monitoring tip

LemWatch detects Cloudflare-specific errors and provides targeted troubleshooting advice for CDN-related issues.
