Cannot access Webmin remotely anymore

SYSTEM INFORMATION
OS type and version Ubuntu 22.04
Webmin version Most recent

Hi team,

I am unsure what would have changed but I am unable to access Webmin remotely anymore. I am running Ubuntu, how can I find out what firewalls are running? I have a feeling that is the issue, because web sites and emails work fine, and I can view Webmin locally.

Thank you in advance,

EDIT* I may have spoken too soon, I created an FTP account and can login – but I cannot view the directory…

What do you mean you can view locally, your running webmin on a local network?
Also if this is webmin only machine what Firewall service do you using.
Maybe this command firewall-cmd --list-all-zones and look for the public zone and see if port 10000 is open.
