Authentication with _paramiko_auth_password failed: Authentication timeout

[nskalis]

Hi,

Could you please advise on why I get the following error message when trying to login on a ios_xr device:

account = Exscript.protocols.Account("xxx", "xxx") 
conn = Exscript.protocols.SSH2(driver="ios_xr", connect_timeout=10, debug=9)
