My domain is:
[mr-kryuchkov.ru]
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
Synology DSM
I can not create certificate with this error:
‘Failed to connect to Let’s Encrypt. Make sure the domain name is valid.’
Port 80 and 443 open. This can also be checked here.
I also tried to get a certificate via ssh using the command:
/usr/syno/sbin/syno-letsencrypt new-cert -d nas.mr-kryuchkov.ru -m admin@mr-kryuchkov.ru -v
And this is the response I got:
