@<1658281099807166464:profile|SmallCamel52> which agent version are you using?

I managed to solve the issue by debugging the agent. I found out that despite the None _company.com:1234/our_gitlab/our_repo.git line I found out that it was actually trying to clone from the url None _company.com:1234/our_gitlab/our_repo.git . The agent host machine therefore didn't try to use the git user, but the session user ec2-user resulting in a permission denied error.

I solved it by adding an entry in the agent's ~/.ssh/config to force the use of user git every time it tries to connect to the host where my gitlab instance is served:

Host ourtools.ourcompany.com
    User git
    Hostname ourtools.ourcompany.com
    IdentityFile ~/.ssh/id_ourcompany

@<1523701087100473344:profile|SuccessfulKoala55> clearml-agent version is 1.6.1

I'm using a self hosted instance of clearml, running on AWS using the AMI clearml-server-1.13.0-414-117

Can you try with the latest version?

@<1523701087100473344:profile|SuccessfulKoala55> Thank your for your advice. I have updated the clearml agent version to 1.7, cleared the cached and forced the server port (it wasn't 22) and also forced the ssh user to git. The error has changed slightly:

1) Make sure you pushed the requested commit:
(repository='

_company.com:1234/our_gitlab/our_repo.git', branch='main', commit_id='f6d54eadf0108a3af243595426a710c150e14861', tag='', docker_cmd=None, entry_point='lstm_training.py', working_dir='tasks')
2) Check if remote-worker has valid credentials [see worker configuration file]

I tried to force the host, but it didn't work - for some reason it started using the agent instance user (ec2-user) instead of git.

Could it be due to the fact that our gitlab instance isn't hosted on our_tools.our_company.com:1234 but on our_tools.our_company.com:1234/our_gitlab/ ?

I confirm that I can successfully clone the repo from a newly created shell directly on the clearml agent server using the url it printed in the logs:

_company.com:1234/our_gitlab/our_repo.git

yup, I'll try and let you know

Thanks. Make sure to delete the agent's VCS cache before trying again
