I recently generated a UCC for

  • domain1.com
  • *.domain1.com
  • domain2.com
  • *.domain2.com

now when i visit http://domain1.com in Firefox i get:

domain1.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown.
The certificate is only valid for the following names:
  *.domain1.com , domain2.com , *.domain2.com

(Error code: sec_error_unknown_issuer)

It complaints that the SSL is

  • Issued by a not trusted authority - which is fine...
  • And its not valid for domain in question

Here is my SSL Cert in text form:

You need to include domain1.com as a Subject Alternative Name. Most browsers will ignore the common name in the subject if there are Subject Alternative Names present. That is why Firefox thinks that the certificate is not valid for https://domain1.com
