[Xen-users] XCP xe cli Error: Connection reset by peer (calling read )

["martinu@xxxxxxxxxxxx" <martinu@xxxxxxxxxxxx>]

Hello,

When I connect to XCP pool master from remote host using OpenXenCenter, 
it's work, but on same host with xe cli, I receive error "Error: 
Connection reset by peer (calling read )":
$ xe help -debug -s X.X.X.X -pwf pwd.sec

stunnel: stunnel has pidty: (StdFork 19607)

stunnel: success: Log from stunnel: []
Error: Connection reset by peer (calling read )

I test xe from rpm and xe from pool master (on local xe work ok), but on 
remote, I still receive error.
Thank you.
