Bucharest Cloudflare Error | HTTP 522: Connection timed out error.

The “Bucharest Cloudflare error” generally refers to an instance where Cloudflare’s data center in Bucharest, Romania, experiences elevated error rates, most commonly the HTTP 522: Connection timed out error.

This is not a unique type of error, but rather a regional manifestation of a common Cloudflare error.

🛑 What Cloudflare Error 522 Means

Cloudflare Error 522 signifies a timeout issue during the connection between the Cloudflare server (located in Bucharest in this specific case) and the website’s original hosting server, known as the origin web server.

The process fails because:

• Cloudflare successfully connected to the origin web server.

• The origin web server failed to return a response within the allowed timeout period.

🔍 Common Causes for an Origin Server Timeout

When this error occurs at a specific location like Bucharest, it usually indicates a connectivity problem between that Cloudflare data center and the origin server. Common causes for a general Cloudflare 522 error include:

• Overloaded or Offline Origin Server: The origin web server is too busy, experiencing heavy traffic, or is completely down, causing it to drop or delay requests.

• Firewall Blocking: The hosting provider’s firewall, .htaccess rules, or internal security settings are blocking Cloudflare’s IP addresses. Cloudflare uses a specific range of IP addresses to connect, and if these are rate-limited or blocked, the connection will time out.

• Incorrect IP Address: The A record in Cloudflare’s DNS settings points to an incorrect or old IP address for the origin web server.

• Keepalive Settings Misconfiguration: The origin server may have disabled Keepalives or set a very short timeout, prematurely closing the connection before Cloudflare receives a response.

✅ How to Fix a Cloudflare Error 522

If you are the website owner, the fix involves troubleshooting the origin server and its network:

1. Whitelist Cloudflare IPs: The most critical step is to ensure your origin server’s firewall is configured to allow all current Cloudflare IP ranges.

2. Check Server Status and Resources: Verify that your origin web server is online, not overloaded (check CPU, memory, and bandwidth usage), and is actively accepting HTTP requests on port 80/443.

3. Review DNS Settings: Confirm the IP address in your Cloudflare DNS A record accurately matches the current public IP address of your origin web server.

4. Increase Keepalive Timeout: If necessary, work with your hosting provider to ensure the web server has an adequate Keepalive timeout setting (e.g., at least 90 seconds).

If you are a site visitor, you should report the issue to the website owner or try clearing your browser cache and cookies, or try using a different network, although the problem is almost certainly on the website’s server side.
