At work, Git server has been moved to a new server, which has ssh libs updated. It seems that Sourcetree is using an outdates version of ssh, which does not connect with the new server.

I have tried to install the last version of putty. When I press pull, nothing happens, I have watched traffic with whireshark.

However, with git bash everything is working as expectec, I copy & paste commands from sourcetree and it works.

Thanks a lot, best regards.
