Hi all,

I’m new with ansible and I trying to connect ansible version 2.9 runs on CentOS with EXOS switch. I tried to connect via SSH using certificates, I put the pub certificate into EXOS switch and try to use command ssh-copy-id, but fails.  
In addiction I try to connect using some commands into yaml file, like:

- ansible\_network\_os: exos
- ansible\_connection: network\_cli  
All my tests are fail and I can’t connection on switch. When I run for example ansible ‘device name’ -m ping the system show me this error.

UNREACHABLE! =\> {  
“changed”: false,  
“msg”: “Failed to connect to the host via ssh: user@device: Permission denied (publickey,password).”,  
“unreachable”: true

Anybody can help me with that ?
