Clone wiki repos with Git using SSH - not working

I'm having the same problem with BCLOUD-4036, but the same approach did not work

I've made a public key, registered it to bitbucket. \\\
Both ssh and https method works fine for the source category. However, for the wiki category, only the https works and ssh fails with {{

{ fatal: The remote end hung up unexpectedly }

}}

Here are the addresses I've used:

• source-https: {{ {https://jangxyz@bitbucket.org/jangxyz/notifier.git}

  }}

• source-ssh: {{ {git@bitbucket.org:jangxyz/notifier.git}

  }}

• wiki-https: {{ {https://jangxyz@bitbucket.org/jangxyz/notifier.git/wiki}

  }}

• wiki-ssh (doesn't work!): {{ {git@bitbucket.org:jangxyz/notifier.git/wiki}

  }}
