Wildcard Certificate "Invalid" on Subdomain

Hi there,

I have a domain (example.com) which has a universal SSL certificate for the following hosts:

  • *.example.com
  • example.com

I have also created a page rule (forwarding URL) to redirect all requests from subdomain.example.com to externaldomain.com/path/to/site (I have set up the appropriate CNAME: subdomain → example.com → proxied).

The issue that I’m running into is that when I load subdomain.example.com on a browser, I get the following error: Error 526 - The origin web server does not have a valid SSL certificate. This error occurs even though the SSL certificate is showing as valid on the browser.

Does anyone have any suggestions for fixing this?

what is your domain name?
and what is your subdomain name?
