Unable to ssh with key pair - Ubuntu (permission denied)

Hi Everyone,

I am unable to login to Ubuntu instance i created using key based auth from horizon. Before launching i created the key, saved on the private key on my MAC and then allocated a floating IP. I am allowing all traffic from security rules but when i try to SSH into it fails with "Permission denied (Public key) error. I have pasted the verbose logs to provide more info. Has anyone faced this issue? I will appreciate if someone can help with this issue please.
