Unobserved task exception caught while calling ConnectAsync #61

How should I handle this internal exception which is thrown by Client.ConnectAsync? I received this exception while trying to connect to a host which was temporarily down and connection timed out.

This is the entire stacktrace, nothing was removed. I have a handler for unobserved task exceptions which only logs the message (as below).

00:36:51.305 ERROR  [ThrId=02] Unobserved task exception caught in the main AppDomain. System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (60): Operation timed out [::ffff:172.16.x.y]:15019

There shouldn't be any unobserved tasks, it just sounds like a bug that needs to be fixed.
