KES application not getting licensed/activated by Kaspersky Next EDR cloud

[Okiwaso]

I am working with the latest version (as of May26-25) of a trial version of Kaspersky Next EDR Optimum and I used the "send email" function to my device to have it install Kaspersky Endpoint Security for Windows  ver 12.8.0.505 BUT it is not getting activated with a license from Next EDR Optimum.

In Next EDR Optimum I created the user and added the users email, then I used "Send Instructions" so the user (me in this case) could install KES.  On my Windows 10 Professional machine ver 22H2 that is joined to an Active Directory domain.  I receive the email from Next EDR Optimum and click the link which downloads KES Cloud ver 12.8.0.505 from my cloud server (Next EDR Optimum).  Then I start the install and it installs the Network Agent, checks connection to administration server (cloud server) and then installs KES cloud ver 12.8.0.505.   After a few minutes this device shows up in my cloud server's DEVICES section.   Also on the Windows 10 machine's KES it says "Managed by security policy" and also says "Managed by sxxx.cloud.kaspersky.com" BUT in the LICENSE section of KES it says "the application is not activated.  To enable the full functionality of the application, active Kaspersky Endpoint Security" and has links to buy a license or activate the application using a new license and in the UPDATE section of KES the "Run Update" button is greyed out.

In my trial cloud server's Information Panel/Licenses section it says I am using 1/100 trial licenses and also says "each license covers one desktop, laptop, or file server and two mobile devices" so it should have activated KES Cloud that was installed on my Windows 10 Professional machine.

In this Kaspersky KB video "How to connect devices (email) in Kaspersky Endpoint Security Cloud" at 0:33 in the video it says "The Kaspersky Endpoint Security application might not activate during the installation, but it will receive the license as soon as it connects to the server in the cloud", but several hours have passed and the KES Network Agent has connected to my cloud server many times.
I even used the Network Agent Klnagchk utility to manually verify connection between the agent and the Next EDR Optimum cloud server/administration server and there were no issues.

Can anyone offer suggestions on why this does not seem to be working as advertised?

Thank you Tahmeed702, but I already verified that the Network Agent could communicate to the Administration Server by using klcsngtgui.exe and running klnagchk without any SSL errors and I could also telnet to the Administration Server so my firewall is not blocking it

What is Distribution package version , you may imply license manually

 

[Okiwaso]

the distribution package version is Kaspersky Endpoint Security for Windows (12.8.0.505)

What do you mean "imply" license manually?

Enter License from this section of Keswin

Thanks Tahmeed, its good to know that I can just enter the Kaspersky Next EDR license activation code or key file into the Kaspersky Endpoint Security application if needed.

But I am currently working with a 30 day trial of Kaspersky Next EDR and it does not tell me the license activation code or key file

Then Download Distribution Package Again and then Install it in the workstations

The problem was "SSL Client Inspection" was enabled on my firewall which pushed out a certificate to decrypt and then re-encrypt SSL encrypted traffic on workstations and servers.

This prevented the activation of KES by Next EDR cloud

Exactly, if there is a tool that inspects traffic from Kaspersky URLs, you will have problems activating the Endpoint using the code. Unfortunately, I went through this and it was through a detail in the documentation that saved me.
https://support.kaspersky.com/help/KSC/15.1/en-US/255242.htm

I only validated this issue because the client in question was On-Premise and changed to KSC CC and previously it used the key file and not the activation code. So, for new hosts, it was only possible to activate via activation code.
