In this 2026 Cloudflare 523 Error Guide, you’ll learn how to fix the “Origin Unreachable” error, which appears when Cloudflare cannot route traffic to your server due to incorrect DNS records, missing IP addresses, or upstream network failures. This guide shows you how to trace and repair the connection.

🔹 What You’ll Learn:
-How To Verify Your Server IP Address Is Correct
-How To Detect DNS Propagation Problems
-How To Identify Routing Or ASN Issues
-How To Confirm Your Hosting Network Is Online
-How To Reconnect Origin Servers To Cloudflare

💡 Pro Tip: A 523 error almost always means your DNS is pointing to the wrong place. If you recently migrated hosting, updated servers, or changed IPs, make sure Cloudflare DNS reflects the new values. For advanced setups using load balancers or multiple origins, test each one individually. Keep a DNS backup file so you can restore settings instantly after migrations.
