Dear Customer,
Thanks for your query.
It seems that the local HL key is visible in the Admin Control Center.
Please follow the given instructions in order to see all the HL keys available in the network and share the results:
1. Open the Admin Control Center and go to 'Configuration' page ( http://localhost:1947/_int_/config.html )
2. Go to the 'Access to Remote License Managers' tab, CHECK the below mentioned options and click SUBMIT.
Allow Access to Remote Licenses
Broadcast Search for Remote Licenses
Note: You may experience a delay of a few minutes before your changes take effect.
Kindly Reopen the Admin Control Center ( http://localhost:1947/_int_/devices.html ) after a few minutes and all the Sentinel HL keys in the network should start getting visible.
The same settings need to be applied on other machine to see the HL keys available in the network from that machine.
Feel free to get back to us.
Thank You,
Gaurav Bhanot
