License all of a sudden stopped working notification. How to resolve?

I checked my account, all is fine. It was working before but now saying it's not.

Is the license server down? Or is there a way to fix this...




Howdy -- what error is it that you're receiving?

Also, what output do you receive when running this command on your server:

ping -c 1

It pings correctly.

I receive a 0% packet loss.

The error is directly under System Information in Yellow/Goldish color. Under the system updates notification area.

" Warning! A problem was detected with your Virtualmin license : An error occurred checking the licence : Invalid host or serial number A renewal can be purchased at "

It just popped up out of nowhere. Valid though here on the site. All is fine... not sure what's wrong.

What is the output of this command:

virtualmin licence-info


Command was not found

I know it's spelled weird, but it's actually "virtualmin licence-info" with two c's in it.

Jamie is from Australia, and likes to spell things in unusual ways :-)

virtualmin licence-info : (OUTPUT):

Serial number: GPL License key: GPL Expiry date: [blank] Virtual servers: 5 Maximum servers: 10 Servers left: 5

Hmm, how did you initially install Virtualmin?

Did you install Virtualmin GPL, and then later upgrade to Pro? Or was Virtualmin Pro what was initially installed onto your server?


To be honest, I don't remember. Between the last ubuntu server and now this centos installation. I can't remember.

I'm guessing it was the GPL and then installed the license after installation.

It was working great... then just popped up.

If you look under System Settings, do you see a "Upgrade to Pro" option?


Nope, I sure don't.

What is the output of these commands:

rpm -qa | grep webmin-virtual-server
cat /etc/virtualmin-license

SerialNumber=GPL LicenseKey=GPL

I think this happened after adding (my main hostname for the server and webmin) as a Virtual Server.

Yeah that's really odd!

What's the output of this command here:

cat /etc/yum.repos.d/virtualmin.repo

Okay, that looks good.

Here is what I would do.

Open the file /etc/virtualmin-license in a text editor, and then add your serial number and license key there in place of the words "GPL".

Then, restart Webmin.

After that, it should get you up and running again.

Okay. After using nano and replacing GPL with the proper serial and key. I am now receiving the following:

Now re-checking your Virtualmin license .. .. a problem was detected : Failed to contact licence server : Download timed out

This was even after restarting webmin.service

There actually is a problem with the license server at the moment :-)

Give it a few hours, and see if it's better at that point.

All works fine now. Thanks! Solved!
