Can't push with git ionic master

Hi guys,
I explain briefly my problem : I liked my app with ionic Appflow and asked them to create ssh keys for me, but I’m stupid so I forgot my passphrase ans didn’t know how to solve it… So I deleted the ssh keys files in .ssh\ionic, I thought re-running ionic link would solve the problem asking me once more for ssh keys. But actually no, even with an other app, the message for ssh keys doen’t show up again, and I have no way to solve it… “git add .” and “git commit -m ‘blabla’” work but "git push ionic master " doesn’t. I have the following error then :
error%20git%20ssh

Any idea ?
Thanks

Remove keys in appflow console (ionic.io)?
