hi @ivgenij
check your apache host configurations
i can see you are hosting both services on the same IP so the logical conclusion is that the difference is in the host configurations
the certificate seems to be valid however your OCSP configuration seems to be of

if you compare your two sites with sslalbs

the other thing that you may want to look at is that you are sending a certificate for non SNI queries which doesn't match
it may be a good idea to fix it as other have had trouble with google treating that behavior as a self signed certificate
