This is a network problem between the clients and the server, you need to investigate that part.

Can you help in knowing how to investigate that in detail as telnet we have tried

You can setup some iperf testing with an external service to monitor the connection between those and see is that stable.
Yeah, everything depends on the provider, tools, vms you use and debugging network problems is out of topic for this forum.

It can be problem with the server connectivity if everyone is experiencing this at the same time. Or it can be a problem with connectivity on the client side if just that client is experiencing it.
