Github: Permission denied (publickey) - github

Question

Update
Ran into this again today - when my work laptop was taken home - appears that a Window domain might be the underlying issue. Found the solution here:
SSH is looking in the wrong place for the public/private key pair on Windows
Original Question
I've had Git working fine for the last few months, this morning I try and make a push and I'm asked to confirm RSA cert for the IP - I double check github IP and it's ok so I add the certificate. But I'm getting:
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
When I try to push or pull.
I read Git - Permission denied (publickey) and tried adding my key again to Github but I'm told:
Key is already in use
Running
ssh -vT git#github.com
Retuns:

Can anyone point me in the right direction?

Answer 1

Seems like you have a bunch of private keys:
debug1: Trying private key: /p/.ssh/identity
debug1: Trying private key: /p/.ssh/id_rsa
debug1: Trying private key: /p/.ssh/id_dsa
Do you recognize any of these?
You might try to specify the key to be used with -i:
ssh -i /path/to/key -vT git#github.com
Maybe this will help.

Answer 2

I ran into this same issue today. My private key wasn't owned by the account I was logged in with.
For anyone else make sure that your account is the owner of the key. In my case it wasn't as it was copied from another account.
Running ssh -i /path/to/key -vT git#github.com as noted by #lum showed me that I didn't have permission to access my private key. Changing owner on the key fixed my issue.
debug1: could not open key file '/home/matt/.ssh/id_rsa': Permission denied
Hope this helps future people.

Answer 3

copy .ssh folder of C:\Users{Administrator}.ssh to git's working directory
