Solved: Error 526 Invalid SSL Certificate
Getting Error 526: Invalid SSL certificate Cloudflare error.
Cause of the problem
Error 526 indicates Cloudflare is unable to successfully validate the SSL certificate on the origin web server and the SSL setting in the Cloudflare SSL/TLS app is set to Full SSL (Strict) for the website.
- If the origin server is configured to use a self-signed certificate, install
a valid certificate on your origin server. To test to see if your origin has
a self-signed certificate, run the following cURL command and replace the
http://example.comwith your domain and
126.96.36.199with your origin IP.
curl -svo /dev/null --resolve example.com:443:188.8.131.52 https://example.com/
The response from an origin server with a self-signed certificate will
SSL certificate problem: self signed certificate. A self-signed
certificate secures the connection between Cloudflare and your origin but will
cause a 526 error when you try to connect to the origin directly.

- Check to make sure the requested domain name (hostname) is in the certificate’s Common Name or Subject Alternative Name (SAN) configuration
