Git Submodule - Permission Denied

Question

I am not able to clone the submodule existing within my private git repository. I do have access to entire repository,

Have used the below commands but dint work, pleas

Answer 1

In my case the issue was caused by console which did not ask me for a password. Solution was to change the console from CMDER to Gitbash. When I used CMDER it does not show the password window which caused this access denied issue.
