Failed to contact licence server??

Help! (Home for newbies)

I installed Virtualmin on my server. It worked fine until the company that I colo my server with gave me a new range of IP address allocation.

When I logged in the control panel, I received the following warning:

"A problem was detected with your Virtualmin licence :
Failed to contact licence server : Failed to lookup IP address for software.virtualmin.com"

I clicked on "Re-check License Status" and received an error message:

"Now re-checking your Virtualmin licence …
… a problem was detected : Failed to contact licence server : Failed to lookup IP address for software.virtualmin.com"

Can somebody tell me what has happened and how to fix it?

Thanks for your help!

A few things I can think of:

  1. Is your DNS working properly, the "Failed to lookup" error may mean its not.
  2. Is the colo/your firewall blocking some packets for some reason?
    Maybe temporarily allow all to and from software.virtualmin.com, see if that works
