My domain is: laurenscantorij.nl
It is run on a hosting with DirectAdmin, with automated LetsEncrypt Certs.
I managed to create a certificate for this domain and it works ok.
But… I added 5 domain pointers (as alias), from which the domain laurenscollegiumrotterdam.nl is one of them. I want to create a new certificate which include the primary, but also all secondary domains.
When I then create this certificate in DirectAdmin, I can select these secondary domains in the list of Let’s Encrypt Certificate Entries.
However when I try to create this certificate, it gives an error for the first of the secondary domain:
Getting challenge for laurenscantorij.nl from acme-server…
Waiting for domain verification…
Challenge is valid.
Getting challenge for laurenscollegiumrotterdam.nl from acme-server…
Waiting for domain verification…
Challenge is invalid. Details: DNS problem: SERVFAIL looking up A for laurenscollegiumrotterdam.nl. Exiting…
The same response I get when selecting one of the other secondary domains.
As far as I can see, there is a normal entry for A in the DNS of the secondary laurenscollegiumrotterdam.nl.
Can you please help me out on this?
