Can't clone private project sourcetree

[Felipe Fonseca]

Hi!

I have many problems with clone a github private project since yesterday.

I always used https to clone projects, but since yesterday i can't clone/pull/push, i receive rpc erros.

I read many sites and i change autentication to ssh. Yesterday i could clone normally. 

But today, i receive the error:

github@github.com: Permission denied (publickey)

When i type ssh - T git@github.com, shows me that correctly authenticated.

I don't know what to do anymore.

Any ideas?
