'Missing' redgate.com-activated licenses in Redgate Monitor

You are tying to allocate licenses from red-gate.com to servers, in Redgate Monitor (Configuration > Licensing). Licenses you believe should be available to allocate to your servers are not. This could simply mean that someone else has used the licenses on another installation. However, 'missing' licenses can also be caused by:

• User being incorrectly added to the license
• Old serial key activations are still consuming licenses having switched to redgate.com licenses

Zero licenses available having switched from serial key to redgate.com licenses 

When you are trying to dynamically switch your perpetual licenses from serial key to the RedgateID-based process, you find that after adding your license via the RedgateID process your Number of licenses still shows as '0'. 

This may be due to old serial key activations of your license still being present in the Redgate licensing portal, having previously activated your license more than once, such as if you had previously activated serial key across other base monitors on your network. It may also be due to your Redgate Monitor webserver being unable to connect to the Redgate Client Service. 

Resolution 1

1. Log on to the Redgate licence portal and go to the licenses tab, or alternatively you can also click “Allocate your licences” from the Redgate Monitor licence page, and then “View licence details”.
2. Select the applicable licence and on the Users tab. You will see something like the following (you may see more or fewer activations than this): 
   
   
   
3. Remove any old serial key activations, these look like “xxxx-xxxx-xxxx-xxxx”. If you see “<installation name>” then leave those in place.  
4. Return to Redgate Monitor (Configuration > Licensing) and refresh the browser. The Licensing table should now show  the correct number of licenses. 
5. Click Allocate you licenses to confirm that all licenses are now listed as "Devices: (<installation_name>)".

By removing those old activations and adding your licenses with your RedgateID you will be able to apply the same license across multiple base monitor installations. In the past this would have required you to split the license. 

Resolution 2

If you are still showing '0' under Number of licenses after trying the above steps then the cause could be that your webserver isn't connecting to Redgate.

 In the case of Redgate Monitor, all the webserver needs to contact is permits.red-gate.com via HTTPS (on default port of 443). It's the only endpoint it uses for new licensing.

To verify if there is block, log into the host running the web server and try to fetch https://permits.red-gate.com/test in Powershell whilst running in the user context that the web server runs in:

">Invoke-WebRequest https://permits.red-gate.com/test"

To resolve this you will need to add permits.red-gate.com to the AllowList on your Firewall. This should allow Redgate Monitor to connect to Redgate and fetch the license information. 

Go back to your Redgate Monitor webserver and refresh the license configuration page. If all is working then the Number of licenses should reflect correctly.
