HTTP Status CodeDown

502 Bad Gateway

A server acting as a proxy received an invalid response from an upstream server. Often a sign of an overloaded backend.

Service appears unreachable or completely offline.

What to do

Wait a minute and try again. Check the site's status page — 502s often indicate a backend deployment or infrastructure issue.

Typical wait time

Typically resolves in minutes. Persistent 502s may indicate a longer backend outage.

What to do next

  1. Check DNS records with a tool like dig, nslookup, or an online DNS lookup.
  2. Verify SSL certificate expiration in your browser or with an SSL checker.
  3. Review HTTP status codes — 5xx means a server-side problem, 4xx means a client-side error.
  4. Check for redirect loops or misconfigured headers.
  5. Check your hosting provider or CDN's status page.
  6. Use our Website Down Checker to test the domain from our servers.
