How to fix license issue

SYSTEM INFORMATION
OS type and version REQUIRED
Virtualmin version REQUIRED

I am getting this error

Warning!
A problem was detected with your Virtualmin license:
Your serial number xxxx is licensed for only 1 server, but it is currently being used on 2 servers. Unless this license is being used temporarily for migration to a new server, you must purchase a separate license for use on this server. A grace period of 21 days is left for managing the migration of the license to a new server. An additional license can be purchased at Virtualmin Shop.

The thing is that I had to rebuild the server so how do i fix this?

I had same warning and it will resolve itself in time. Think it took a week for my error to resolve.

Post when I asked about the warning:

For now just focus on rebuilding server :grin:

This exactly should answer your question!

I just had this when I tried pro to test Podman on a dev machine. After testing the production machine showed that error for 3 or 4 days and went away.
So just wait for a week.

That should be about 48 hours, yet:
