I am getting an exception running this code:

            _connection = new SeqConnection("http://fc2026:5341");
            _appInstances = _connection.AppInstances;
            var apps = await _appInstances.ListAsync();

I am able to produce the exception in my VS2013 debugger and have stepped into the Seq.Api assembly method HttpGetAsync<>(string), but am not really sure how to proceed from here.

The Exception:

System.ArgumentNullException occurred
  _HResult=-2147467261
  _message=Value cannot be null.
  HResult=-2147467261
  IsTransient=false
  Message=Value cannot be null.
Parameter name: initialValue
  Source=Newtonsoft.Json
  ParamName=initialValue
