Common issues

1. Site opens for me but not for my users

Regional blocking or ISP-level issues. Have them try ping + traceroute, or test from a different network (mobile vs wifi).

2. Site responds slowly — how to diagnose?

Response times above 1s usually mean TTFB or server overload. Run the PageSpeed check or Ping to see where the lag is.

3. HTTPS / SSL certificate errors

Use the SSL checker — it reports expiry date, chain validity, cipher suite, and PFS status. Most browser warnings come from expired certs or missing intermediate CA.

4. Timeout / no response

DNS misconfiguration, firewall, or dead server. Start with DNS lookup + Ping to localise the failure.

5. What do HTTP 403 / 429 / 503 codes mean?

See our HTTP status code reference. 403 = forbidden (access rules), 429 = rate-limited, 503 = server temporarily down or blocking.

6. DNS resolves slowly or inconsistently

Try DNS propagation check — shows the resolved IP from 8+ global resolvers. Inconsistent answers mean DNS is still propagating.

7. Site loads but assets (images, CSS) are broken

CDN or sub-domain issue. Inspect the HTTP headers above for Cache-Control + CDN-specific headers (X-Served-By, cf-ray). Run the broken-links checker for a full audit.

8. How to contact the site's tech support

Most sites list support contacts at /contact, /help, /support, or in the footer. WHOIS may expose an abuse@ email: look up WHOIS.
