Cannot run jobs - unable to clone git repository

Hi, I developing models and pushing them successfully to the connected Gitlab repo through the Develop IDE. Now I wanted to schedule a job for the developed models, however the job fails on the very first step being unable to Clone the repo throwing the error

HTTP Basic: Access denied. The provided password or token is incorrect or your account has 2FA enabled and you must use a personal access token instead of a password. See https://gitlab.com/help/topics/git/troubleshooting_git#error-on-git-fetch-http-basic-access-denied

Can you guide me where is the issue? I was also looking in the Settings under Integrations, but only Github option is displayed there.

I’m using the free Developer plan.
