Joyent no.de and Cloud9 ide

Hi have copied my cloud9 ide SSH key in my account settings in joyent no.de. When I launch "git push mywebsite.no.de master" in my cloud9 ide console I get the following errors:

Warning: Permanently added 'mywebsite.no.de,64.30.136.97' (RSA) to the list of known hosts.
Permission denied (gssapi-keyex,gssapi-with-mic,publickey).
fatal: The remote end hung up unexpectedly

Could this be related to the following piece of information not being set-up any where? I think its a config for cloud9 ide, but How to set it up?

Host mywebsite.no.de
Port 26674
User node
ForwardAgent yes

For node.js, git, cloud9 and joyent noobs, like me, this is how you do it:

• Go to your cloud9 account-> Dashboard->Show your SSH key and copy it
• SSH to your joyent node machine.
• add to your ~/.ssh/authorized_keys the pubkey you just copied from Cloud9 (just copy it in that file, if it doesn't exist)
• Go to Cloud9, to the editor, and in the command line do: git remote add node ssh://node@yourhost.no.de:66666/home/node/repo
• Yes, i know that's not a valid port number, smartass. Put in the port to your no.de machine instead
• Edit something in cloud 9
• git commit -a -m 'Victor rules!'
• git push node master
• Win!
