Tests on Procurve Switch

Hi,

My goal is to pull down the running config. At this point, I’m just trying to run some simple tests on HP 5400zl Series switches.
I’m using ansible 2.1.1.0 on Centos7.

I get different results depending on the connection type and both fail at a point I’m not sure how to troubleshoot.The only real clue I see here is “debug3: mux_client_read_packet: read header failed: Broken pipe”. Any ideas on how to troubleshoot this more or other parameters to tweak? I do have “host_key_checking=false”

Thanks.
