If you changed servers recently, that could cause the problem you’re seeing.
If the license manager sees Virtualmin in use on a given IP, it remembers that for a few days, but it’ll clear out afterwards if that IP is no longer in use.
My suggestion would be to wait a day or two, and if you’re still seeing that message, file a support request using the Support link above, and Jamie can work with you to figure out what’s going wrong.
