[İbrahim Halil Çadırcı]

Hi I want to clone the site via private repo yu cpanel but I get the following error. I created the SSH key from cpanel and defined it via bitbucket.
Error : Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
