I have tried adding the SSH key by project, by account.
I was able to do a git clone of a private repository, but the git push does not work.
It seems it can't find the repository.
Doing this produces the following output.
GIT_SSH_COMMAND="ssh -v" git push
debug1: Authentication succeeded (publickey).
Authenticated to bitbucket.org ([104.192.141.1]:22).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.

debug1: Sending environment.

debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
The requested repository either does not exist or you do not have access. If you believe this repository exists and you have access, make sure you're authenticated.
Any hint?
