I have a .com site that is https with a Comodo certificate via Dreamhost. I also have https://cdn.domain.com with a unique ip address to make it play nice with MaxCDN. The site is run in two languages with WPML (WordPress Multilingual Plugin) and .nl is an alias (Dreamhost calls it site mirroring ) to .com. WPML makes sure all posts in NL are loaded with the .nl domain. Just upgraded WPML to a new system so perhaps that is the issue but I doubt it.
When I opened domain.nl in Firefox just now I had:
domain.nl uses an invalid security certificate. The certificate is not trusted because it is self-signed. The certificate is only valid for sni.dreamhost.com (Error code: sec_error_unknown_issuer)
I decided to request for a new certificate. In Chrome using https://domain.nl I still see a self signed non verified Certificate error. So even though it is Comodo verified now I still get this error..
Server Alias with SSL Certificate Server hostname
My question is, is this adding of a certificate really necessary as .nl is just an alias of .com ? Is there no option to make an alias run without certificate errors on top of a host with a SSL Certificate?
