Website Error Fixes

Each guide answers one question first, is it your device or the website?, then gives step-by-step fixes for visitors and for site owners.

DNS errors

• DNS_PROBE_FINISHED_NXDOMAIN: DNS says the domain or name doesn't exist.

SSL / certificate errors

• ERR_SSL_PROTOCOL_ERROR: the secure connection failed before the page loaded.
• NET::ERR_CERT_DATE_INVALID: the certificate is expired, or your clock is wrong.

Server and CDN errors

• 502 Bad Gateway: a proxy or load balancer got a bad answer from the server behind it.
• Cloudflare error 522: Cloudflare couldn't connect to the website's server in time.
