How to know a websocket connection is still alive

[maso144]

Hi all

I am facing an issue with a GraphQL subscription on the client side. The subscription stops receiving data from server without any evidence of error. I am struggling to find the root cause of this issue.
There are other clients which receive data from the end point at the same time.

I would like to monitor this connection, for example with ping/pong messages, and re-subscribe if server is not responding.
I could not find any .NET code samples for those ping messages, could you please help?

Or is there a better solution for this issue?

Which GraphQL client library are you using on the client side?

I am using these packages:

GraphQL.Client (version 6.0.0)
GraphQL.Client.Abstractions
GraphQL.Client.Abstractions.Websocket
GraphQL.Client.Serializer.Newtonsoft
GraphQL.Primitives

I've moved this discussion to the GraphQL.Client repository. If you have questions regarding the GraphQL.NET server implementation and its options to prevent timeouts via ping/pong, please post them in the GraphQL.NET Server repo under issues or discussions, and I can answer there.

I don't use this library, but perhaps @rose-a can help.
