Openmediavault Certbot and apache 2 problem

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

    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

Hi @onluigi

your domain is invisible ( https://check-your-website.server-daten.de/?q=naszmhome.ddns.net ):

If you want to use http-01 validation, port 80 must be open. Instead, there is a timeout. And https blocks, looks like a firewall.

There are a lot of older Letsencrypt certificates:

Total 29. Perhaps you have used tls-sni-01 - validation, that's deprecated.

If it is a home server, check your router settings:

external port 80 -> internal port 80 must answer.

Thanks a lot JuergenAuer, i forgot to change my old server ip on my router related to port 80.
Your explanation is awesome for me!
