Ansible 'unreachable, permission denied' error

[spurs]

I was able to ping from the control node to 2 manage nodes.

It showed unreachable error.. and permission denied error makes me more confused. 

The user2 is in full control access with sudo privileges.

How can I resolve this error?

@spurs what about the ssh configuration ?  Are you able to connect to the servers using ssh command ? Are you using the correct password ( for both ssh and privilege escalation)  ? Increase the verbosity mode like -vv or -vvv to see if you can get anything in the debug mode.

Yes, I was able to connect to the managed nodes by ssh as well.

From the control node, I created ssh key and copied it to managed nodes.

After that, I connected to each managed node by ssh to make sure.

omg now it worked. I said that I copied the key but actually I didn't

Great @spurs ! Glad that it is working now for you.
