Check that your ingress load balancer supports WebSockets and doesn't timeout long lived connections. Some cloud providers timeout connections after a few seconds by default. You may need to increase it.

Thanks for the quick response @jondubois. I really appreciate it. But even if i disable the ping time out, that is
let agOptions = { pingTimeoutDisabled: true };
It still gets disconnected. The other thing is, its quite inconsistent. For some clients its 40s for others its 80-90s. Also it's not an issue from the load balancer side as the sticky session time out has been set to more than 1000 seconds.
Please suggest the right configuration for the load balancer if required.

Another possibility is that if your client and server major versions are different (especially those before v14 versus v15+), it can lead to timeout issues as the timeout message is different. In the older versions, the protocol used #1
and #2
messages for ping and pong but in newer versions it uses empty strings (to save bandwidth).
If you want to use new clients with old servers, you can run the latest client in compatibility mode. See https://github.com/SocketCluster/socketcluster#compatibility-mode
