I'm not able to clone or to create a new repository. I've generated a new SSH key in putty. So when I try to follow the instruction (https://community.atlassian.com/t5/Sourcetree-questions/SourceTree-error-The-server-s-host-key-is-not-cached-in-the/qaq-p/1410001) I get fatal errors:
>C:\Users\User\AppData\Local\SourceTree\app-3.4.9\tools\putty\plink.exe bitbucket.org
login as: ***
FATAL ERROR: No supported authentication methods available (server sent: publickey)
