Problem with SSH and GitHub

Hi guys, I'm trying to checkout a github repository and I'm having some problems.

I have setup my ssh keys and I can do a ssh git@github.com.

However, when I try to check out a project from git, I get this exception.

SSH: authentication methods: [publickey, keyboard-interactive, password] last successful method: 
java.io.IOException: Authentication failed: 
     at org.jetbrains.git4idea.ssh.SSHMain.authenticate(SSHMain.java:280)
     at org.jetbrains.git4idea.ssh.SSHMain.start(SSHMain.java:155)
     at org.jetbrains.git4idea.ssh.SSHMain.main(SSHMain.java:135)
fatal: The remote end hung up unexpectedly

Any ideas.  I'm new to PyCharm.

Thank you.
