Heartbeat requests suddenly stopping to cluster members

[rvenancio]

The C# client (version 3.9.1) is connecting successfully to server nodes (also 3.9.1). After that, It starts sending heartbeat requests to the server nodes, but in about 2minutes it suddenly stops as we can see in the following logs.

After 5minutes, the server nodes kick the client due to inactivity.

Anyone is also facing this issue?
