I have an origin certificate that I generated from Cloudflare that expires on
2035-07-02 that I downloaded and added to my server.
The hosts listed on this certificate are:
*.domain.com, domain.com (ssl_tls.crypto_hosts)
The status of this certificate is
active and I ran my subdomain through https://www.sslshopper.com/ssl-checker with 0 errors.
I have my encryption set to full (strict) and my full domain (
domain.com) works as expected, however my subdomain (
sub.domain.com) is throwing a 526 error.
I’ve spent two days on this and am out of ideas. Can someone help me understand why my configuration is causing an error only on my subdomain?
