My nextcloud was running fine for some month.
I started the renewal of my letencrypt cert as ncp user on port 4443.
As far as I could see that worked fine.
After a reboot all ports were closed byside of the ssh prot.
The reason was, that the certs were no longer on
/etc/letsencrypt/live/mydomain.xyz/
but in
/etc/letsencrypt/live/mydomain.yxz-0001/
the difference ist the**-0001**
My quick fix was a symlink
sudo ln -s /etc/letsencrypt/live/mydomain.yxz-0001 /etc/letsencrypt/live/mydomain.yxz
After that I could access nextcloud again.
Is this my mastake, or is this a bug?
What can I do to avoid this problem in the future?
Tx and greetings Leon
