Followup of NextCloudPi certbot doesn't work:
as the title says… nc-Letsenrypt-routine works… but even if I would move the sub.domain.tld into sub.domain.tld-old (as @OliverV) suggested in his linked posting the renewal ran by nc-config (from commandline) would end up making a whole new file called sub.domain.tld-0001 - which, of course, wouldn’t be recognized by apache at all. unless you’d tweak given apache-files to recognize them).
so right now everything is working again. but somehow this seems to be a misbehaviour of the renewal-procedure. I don’t know how to solve it.
I’m running NC 18.0.5 on a nc-VM hosted on my network at office/home.
ncp v 1.28.0
(if you’d need more info, jst let me know and I’m gonna provide that asap)
looking foward to any helpful comment
