We already tried that. But in the name of troubleshooting here are the steps we just took after your reply:
Logged into cPanel
Click SSL/TLS
Click Generate, view, upload, or delete SSL certificates
The Origin CA Root Cert shows as expiring 8/15/29 and says - Self Signed - as issuer
Deleted cert
Tried site again, still no SSL
Tried SSL Checker again, still same error
Did NOT reinstall RSA cert again. Thing is, this morning things were working fine without the RSA Cert and our original CF cert from May that expired in May 2036. I uninstalled and deleted that cert and created a new one and we get that intermediate cert has expired error message still, even with the new cert that expires in August 2036.
OK, We have it all squared now. We figured out the issue. Our DNS records were not Proxied, we changed that and the certs are valid now and everything is working as it should. Sometimes it’s the simple things. Thanks
