Greetings!
I am pretty new to Cloudron - therefore first of all a very big thank you for the incredible valuable product, highly appreciated.
If have just setup an instance of NextCloud at 'nxtcld.drbigman.org' - with domain 'drbigman.org' provided by porkbun. So far everything is working perfectly fine.
However, when accessing base domain 'drbigman.org', a security warning is displayed and self-signed certificate (as provided for setup of my.drbigman.org from Cloudron) needs to be accepted.
This issue is somewhat similar to the one described at https://forum.cloudron.io/topic/8270/lets-encrypt - however, in my case there is not even any web service configured for the base domain.
As already mentioned: not a real problem at all. Besides showing a warning when accessing base domain, other effects include e.g. that SSL Server Test (https://www.ssllabs.com/ssltest/) will complain about a certificate mismatch when checking base domain (checking 'my.drbigman.org' returns perfect A+ for both IPv4/6).
However, when I checked the Let'sEncrypt wildcard certificate as correctly used for 'nxtcld.drbigman.org', I noticed that it appears to only be issued for (wildcard) domains *.drbigman.org - but not in addition for 'drbigman.org', correct?
IIRC, wildcard '.drbigman.org' does not include base domain 'drbigman.org' itself - but only subdomains. Therefore similar 'plain vanilla' certificates are frequently issued for '.drbigman.org, drbigman.org' - so that they also apply for the base domain.
As recommended in ticket mentioned above, I have also renewed all certs thru dashboard - however, problem remains the same.
Is there a certain reason, why LE cert is not issued for '*.drbigman.org, drbigman.org' - or may I have configured something incorrectly?
Many thanks in advance for your support and advice.
