Unable to login to smartconsole

[gemechisd]

We have 2 checkpoint 7000 series appliances in our environment and one open server SMS to manage both gateways. Starting from last week we have faced a problem of connecting to smartconsole through smart console and webGUI. "Unable to connect to server" & "A connection with the server lost error.". Our SMS is installed with a JHF of 161 until today. Early morning I have installed JHF 197. Still the problem persists.

We have 64GB memory and 20 CPU's for our SMS.

What are the main causes and how can i solve it? I appreciate your support on this.

There are many possible causes for this, such as network issues between your PC and the SMS, a firewall in path blocking something, load/resource utilisation issues on the SMS, software issues, all that. Have you run an HCP check on the server to see if there's any issues there?

Can you please run cpwd_admin list on the Security Management Server and share the output. 

It is important to see the CPM and FWM are up and running properly.
