Not able to SSH

I am not able to ssh to one of the EC2 host in AWS:

bash-3.2$ ssh -vvvv -i ~/.ssh/id_rsa_APP_GIT 54.12.34.56 -l b123
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

Though I can telnet it:

bash-3.2$ telnet 54.12.34.56 22
Trying 54.12.34.56...

Appreciate if someone can help in suggesting how to troubleshoot it

It seems to get stuck on the exchange of SSH versions:

debug1: Local version string SSH-2.0-OpenSSH_6.2
ssh_exchange_identification: read: Operation timed out

Might want to check versions on your local machine... Or check local ssh config... Or try by removing old ssh config files if any exist.

Thanks for hint, here my local ssh config, I am using SSH:

bash-3.2$ cat /etc/ssh_config  | grep -v ^# | grep -v ^$
 Host *
   SendEnv LANG LC_*
Host *
    XAuthLocation /opt/X11/bin/xauth
bash-3.2$ cat /etc/sshd_config  | grep -v ^# | grep -v ^$
SyslogFacility AUTHPRIV
AuthorizedKeysFile	.ssh/authorized_keys
UsePrivilegeSeparation sandbox		# Default for new installations.
AcceptEnv LANG LC_*

I think that the problem is here

debug3: Incorrect RSA1 identifier
debug3: Could not load "/Users/user1/.ssh/id_rsa_APP_GIT" as a RSA1 public key

Can you show us the contents of /Users/user1/.ssh/authorized_keys ? This is the user1 public key on the server, not your private key, and it is supposed to be shared so you are not at risk.

Can you check versions on both client and server?
