I'm facing issue while trying to clone a test repo(public) from bitbucket as shown below. Strangely the ssh auth is not going through for bitbucket and works fine for github when same public key is added to both accounts. I'm assuming that there is some sort of ssh negotiation variation between github and bitbucket which doesn't work with version of opnessh on my aix 7.1 server. Any clues what can be done here to find the root cause? Please note that the https clone on bitbucket works just fine.
