I am starting to move stuf over from one server to another. On the both servers I'm running DA. As a test I moved the two least important domains from one server to the other. I only moved the contents for one of the domains, for the other I only moved the domain-name and set up everything from scratch. On both domains I set up ssl with letsencrypt without any problems.
A couple of weeks ago I added two new domains to my new server. Today I tried to add ssl to these domains (DNS is well resolved by now). Just out of curiosity I first tried to use a wildcard, this resulted in the error: DNS challenge test fail for _acme-challenge-test.xxxxxx.nl IN TXT "pre-check", retrying...
Since I really don't have any subdomains yet I just used the top-domain plus the pre-defined set of subdomains, mail, pop, ftp, smtp, www. However, only the top domain, www and mail will get through the check. When I try to add ftp in the set I get: Error: http://ftp.xxxxx.nl/.well-known/acme-challenge/letsencrypt_1589927937 is not reachable. Not really a surprise, since for all I know ftp.domain.nl is not reachable via http... I get the same error for pop and smtp.
What can be going wrong? I did this before but never encountered this problem (I still have 9 domains waiting to be moved on my old server, all have ssl on all subdomains, including pop and ftp). DNS setting on the newly added domains are identical to the two older domains that don't have problems with ftp or smtp subdomains.
PS: I just tried the wildcard option on one of the older domains and there were no errors... It feels like a permissions problem, but I don't know where to start looking.
