Update error-526.mdx

Open Kiki-Y123 opened this issue 4 months ago • 1 comments

added this part:

If you are using self-signed SSL certificate at the origin server, use the following workaround to avoid an HTTP Error 526.

Add your self-signed SSL certificate to the Custom Origin Trust Store. This allows the Cloudflare edge to recognize your self-signed SSL certificate as valid. In your Worker's configuration, enable the cots_on_external_fetch compatibility flag. This flag enables the use of the Custom Origin Trust Store when making external (grey-clouded) subrequests from a Cloudflare Worker.
