Heroku push master ssh problem

I get this when I am trying to push to my Heroku app:

ssh_exchange_identification: 开发者_如何学运维read: Connection reset by peer
fatal: The remote end hung up unexpectedly

I tried regenerating the ssh keys and adding them to the remote, but no joy. Any help. Kinda stuck in a rut here!

EDIT: and now I get the same error from a different app that was working very recently. :/

It is usually usefull to make a:

ssh -vvv yourlogin@heroku

in order to dispay all the operations taking place during the ssh communication.

Various causes can be at the origin of these,

• from a $HOME not correctly defined (usual on Windows where the environment variable %HOME% isn't defined at all by default)
• to an IP conflict address (see this thread) for the SSH daemon.

Heroku is having git problems - see Heroku server status: http://status.heroku.com/

I just started getting this error now.
