I have recently tried (once again) to install Virtualmin on an Ubuntu 18.04 droplet on DigitalOcean, with the following settings:
I believe private networking and/ or IPv6 is causing issues.
Unlike in the previous months where installation would fail to complete at all, this time, Virtualmin installs successfully and I am able to set up my virtual servers just fine. The issue arises when I reboot the droplet. After a reboot, I can no longer SSH into my droplet or access Virtualmin via the web interface. I can only access my droplet through the DigitalOcean console.
I believe there is still some misconfiguration in the networking settings on Virtualmin/ Webmin's part which prevents my setup from working properly. Would appreciate if this could be fixed. Thank you!
