Howdy -- I think we were seeing some symptoms with your setup previously that were looking like they may have been more of a networking, but there are some commands we can use for some troubleshooting to give us a better idea of what's going on there.

What is the output of these commands on your Virtualmin server:

netstat -anlp | grep :10000
dmesg | tail -30
uptime
free -m

Hmm, I'm not seeing any sign that Webmin/Virtualmin isn't running... the process is running there, and there's no kernel messages indicating resource problems.

That likely indicates that there's some sort of network issues that's causing the connection to drop.

A networking issue is unfortunately not something we'd be able to resolve. We're happy to help with Virtualmin problems, but networking issues are a bit outside the scope of our support. Sorry!
