Few devices do not connect to KSN no matter what

[Gabriel Boettcher]

I'm experiencing an issue with a virtual server in our infrastructure. On this server, six devices are unable to connect to Kaspersky Security Network (KSN), no matter what I try. So far, I’ve done the following troubleshooting steps:

• Verified that firewall ports 13111 and 15111 are open.

• Checked whether any proxy might be blocking the connection.

• Confirmed that the KSN proxy server is running properly on the administration servers.

• Allowed the affected devices to connect to KSN directly

• Reviewed and modified all relevant distribution point settings in the Network Agent policy.

• Reviewed and adjusted all proxy configuration options in the KES policy.

Despite all this, the six devices still fail to connect to KSN. I'm looking for suggestions on what else I can check or try to resolve the issue.

Hello,

Please check latest events of those devices, perhaps will give you more information about which is the problem.

Also, my recommendation is open a support ticket in Kaspersky Company Account, attach the getsysteminfo (gsi) of one of the affected devices.

Estou com um problema com um servidor virtual em nossa infraestrutura. Neste servidor, seis dispositivos não conseguem se conectar à Kaspersky Security Network (KSN), não importa o que eu tente. Até agora, executei as seguintes etapas de solução de problemas:

• Foi verificado que as portas de firewall 13111 e 15111 estão abertas.

• Foi verificado se algum proxy pode estar bloqueando a conexão.

• Confirmou que o servidor proxy KSN está sendo executado corretamente nos servidores de administração.

• Permitiu que os dispositivos afetados se conectassem diretamente ao KSN

• Revisou e modificou todas as configurações relevantes do ponto de distribuição na política do Agente de Rede .

• Revisou e ajustou todas as opções de configuração de proxy na política do KES .

Apesar de tudo isso, os seis dispositivos ainda não conseguem se conectar à KSN. Estou buscando sugestões sobre o que mais posso verificar ou tentar resolver o problema.

 

Hello Gabriel, I had a similar problem here, after contacting Kaspersky support level 2, for a specific issue in my environment, I needed to disable the KSN option via https port 17111, do a test by disabling this option.
This option is in the administration server policy.
