I got from root yesterday and today the following:

/var/log/letsencrypt/letsencrypt.log is empty, but there is a
letsencrypt.log-20231224.gz at the same location and same date
with the attached content that didn't help me out.

<p>I believe that your error is located here in the logfile you
attached:</p>
<p>[Sun Dec 24 00:36:43 CET 2023] www.blaettler.legler.org:Verify
error:During secondary validation: DNS problem: NXDOMAIN looking
up A for <a class="moz-txt-link-abbreviated" href="http://www.blaettler.legler.org">www.blaettler.legler.org</a> - check that a DNS record exists

<p>So it is possible that there was a momentary problem with the DNS

<p>Yes, I see that the current certificate is valid until <span

Can anyone, when she/he has some spare time, help me out here,
please? It's really stupid that this occurs right now...

<p>Based on the above, I think that the problem may have been DNS
related. So you might give it another try.</p>
<p>If that fails, something that I find helps in the case of very
old LetsEncrypt sites is to disable the SSL from Site Management,
then manually (via CLI) remove any of the certificates in the
VSITE's certs directory. Then back at the GUI request the
LetsEncrypt again (which you may have to do twice.)</p>
<p>Best of luck, and Merry Christmas. <br>
