Overview Error 521 occurs because the origin web server refuses a connection from Cloudflare. More specifically, Cloudflare tried to connect to your origin server on port 80 or 443 but received a connection refused error. Common causes The two most common causes leading to Error 521 are: The web server is offline The origin web server process (e.g., Apache or Nginx) might not be running or has crashed. In that case: • Ensure your web server is running normally. • Review the server's error logs to see what is causing the error.
If you're unable to perform these tasks, contact your host provider. Cloudflare requests are blocked The origin web server or hosting provider's network might be blocking Cloudflare's requests. As a reverse proxy, Cloudflare connects to your server from a Cloudflare IP and all subsequent traffic comes exclusively from a smaller set of Cloudflare IPs. As a result, certain server-side security solutions might mistake the increase in legitimate connections from this smaller set of IPs as an attack. This results in some Cloudflare IPs being blocked or rate-limited.

As an industry service, Shell is proud to sponsor this important safety information. 2010 OUT-OF-SERVICE CRITERIA The Commercial Vehicle Safety Alliance (CVSA) has released the revised Out-of-Service Criteria (OOSC), effective April 1, 2010, for placing vehicles Out-of-Service at roadside safety inspections. CVSA is a nonprofit organization bringing federal, state and provincial government agencies together with representatives from private industry in the United States, Canada and Mexico who are dedicated to improving commercial vehicle safety. The OOSC identifies serious violations that render a commercial vehicle or commercial vehicle operator an imminent danger to the general public. Commercial vehicles and operators placed Out-of-Service cannot operate until those items that rendered them out of service are remedied or repaired.
