I am unable to clone a Git repository, and getting this error:
krishna.soni@KRISHNACHANDRAS /c/Projects $ git clone http://stage.abc.com:10088/pqr http://<
I had the same error. My solution was to logout and login again as my ssh-agent had become out of sync with the remote ssh key.
Adding this here just in case anyone has seen that the other answers don't seem to apply to their situation.
