ISPConfig SSL certificate

Ok, now I try thanks

 

Basically I have an empty A record that points to the public ip of the server with ISPConfig, the rest of the records I created on CNAME so also webserver. which is the name of the server. So should it work? Thanks

 

What is an empty A record?
Use whatever you use for you servers ultra secret FQDN hostname in the following command in place of the hostname.domain.tld

Code:

dig hostname.domain.tld A

Does the command output a line with A record for that hostname?

 

A record @

 

Although some dns services will allow an empty hostname field to point to the "root" of the fqdn in this case it isn't an empty A record as you state, it contains and @ but they essentially mean the same thing with the @ being more useful to other dns records in some cases.

Here is a question on the subject at serverfault: https://serverfault.com/questions/83874/whats-the-meaning-of-in-a-dns-zone-file

 

Yes, in fact, in the second answer I specified record @ to make it clearer
