Rex can't connect to host

[Andrea Agazzone]

Hi, I'm new with this tool.

I installed it on windows, but when I try to connect to only one host via SSH and execute uptime command, I receive always "Can't connect to [host]".

[2017-04-03 13:57:34] INFO - Running task uptime on [host]

[2017-04-03 13:57:40] WARN - Can't connect to [host]

[2017-04-03 13:57:40] ERROR - 1 out of 1 task(s) failed:

[2017-04-03 13:57:41] ERROR -   uptime failed on [host]

[2017-04-03 13:57:41] ERROR -           Couldn't connect to [host]. at C:/Binaries/Perl/perl/site/lib/Rex/TaskList/Base.pm line 342.

Any suggestion? Via normal SSH it works.

Thanks
