I am having issues with committing changes to my gear. I have tried to run rhc setup, I also deleted my .ssh folder and executed rhc setup again but that also didnt work.
what worked for me was to generate the keys using Git Bash
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
and then add the key to ssh-agent as described here
ssh-agent
