Hello,
I don't know if is this a bug; the problem is present when we use only one IP and have more than one domain or domains+subdomains.
For example:
I have domain.com - sub1.domain.com - sub2.domain.com and only 1 IP for all of them.
I'm using a Comodo Certificate for sub1.domain.com, another one for sub2.domain.com and another one self-signed for domain.com:
domain.com --> Self-signed
sub1.domain.com --> Comodo Certificate A
sub2.domain.com --> Comodo Certificate B
The first one certificate installed was Comodo Certificate A for sub1.domain.com and works ok, no problem.
The second one, Comodo Certificate B for sub2.domain.com also works ok, but, below I explain the problem.
If you use a SSL Checker webs for test sub1.domain.com the response is always ok, it's properly configured. When you check the sub2.domain.com, some checkers says ok, BUT another ones says that the certificate is issued for sub1.domain.com and gives you an error.
The best check:
Code: Select all
openssl s_client -connect domain.com:443 | openssl x509 -text
With this, you can check the only one certificate that it's working properly it's the first one installed, the other ones doesn't not work because says that are issued for sub1.domain.com.
I don't know if it's a bug, but I'm having some problems with certificates in differents subdomains.
Regards.
