Hi guys, i’m newer of this forum and i have to ask your help.
I run openmediavault on my raspberry p3+ and i want to secure it by remote access with my domain.
I went from ubuntu where i used openmediavault on vm and i always follow cerbot guide with no problem.
Run debian 9 (openmediavault) i find this problem:
Apache 2 correctly installed
root@raspberrypi:/# sudo certbot --apache
Saving debug log to /var/log/letsencrypt/letsencrypt.log

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
Can you help me to solve this problem?
thanks a lot
