System.Net.Http.HttpRequestException occured in ping-pong process about slackbotnet

[KonH]

In my fork I have made hotfix, which is not acceptable for normal operation (bot can't read the messages after fail), but at least eliminates the unhandled exception. In our conditions it is suitable as a temporary solution.
For fix bot read ability In next commit I have tried to reconnect after websocket status is not Open. I'm not sure if this is the correct solution, I didn't have enough time to adequately study the project code.

I put in some logic that will retry the reconnect attempts until a new socket connection can be established. My initial tests were just around the tcp connection being dropped and didn't account for a larger network disruption.

v0.8.7 has been released to NuGet with this change. Hopefully this will resolve your issue!
