Cloudflare is a content delivery network that acts as a gateway between users and website servers. When the 526 Invalid SSL certificate status code is received, it means that the HTTP Connection to the origin server cannot be established because the SSL certificate provided by the server is invalid or expired.
This can result in a security risk and may prevent users from accessing the website securely.
In Action
Cloudflare, a content delivery network, acts as an intermediary between users and website servers. If you encounter the 526 Invalid SSL certificate status code, it means Cloudflare couldn’t verify the SSL certificate on the origin server, especially when the SSL/TLS settings in Cloudflare are set to full SSL (Strict).
The main reason for this error is often an expired SSL certificate on the origin server.

When you see the 526 Invalid SSL certificate status code, it means Cloudflare couldn’t verify the SSL certificate on the website’s server. This error usually occurs when the SSL certificate on the server is expired or misconfigured, preventing a secure connection between Cloudflare and the origin server.
