Ansible Role issue with Github

I have recently been tasked to migrate our ansible playbooks and roles over to github from bitbucket as we want to consolidate our systems. I am currently running into a permissions issue when I am trying to call a role from a playbook.

playbook is in it’s own repo (let’s call it pb-repo) and role is in another repo (let’s call it ar-repo).

in bitbucket, it works perfectly fine as I have in the roles/requirements.yml file of the playbook that calls that bitbucket repo

- src: git+ssh//

however, this doesn’t work in github. I have created credentials in awx, uploaded the ssh key into github and it does sync the playbook repo.

roles/requirements.yml for playbook in github

 - src: git+ssh//

error message for reference:

" Permission denied (publickey).  fatal: Could not read from",
    "remote repository.  Please make sure you have the correct access rights and the",
    "repository exists.

I’ve tried recreating the credentials, I matched the credentials to the old credentials. Tried using the old credentials as well without any luck. any ideas?
