Github
$ ssh -T git@github.com $ git@github.com: Permission denied (publickey).
Hmm?
The [.ssh] directory looks fine
Checked logs with
ssh -vT git@github.com
or
ssh -vvv git@github.com
Errors point to the key
Github SSHKey on the web page
It’s gone!
Apparently SSH public keys expire and get deleted automatically
Recreated and set it up. Problem solved.
