Running posh-cisco, version 1.0.3, posh-SSH version 2.2
Running any command against my Catalyst 2960X, 3560X, 3850, or 9300 switches I get: "Exception calling "EndExecute" with "1" argument(s): "An established connection was aborted by the server."
I get the same error using Invoke-SSHCommand directly. Using the stream.writeline and stream.readline methods works.
