Both of are trying to run the same code from the same repository on the same queue and machine.

HI, the agent is configured without password nor user name. As instructed during the installation.

HI Jake, thank you for your help. I set the flag force_git_ssh_protocol to true and it solved the issue. thanks

And as I mentioned the only difference is that it's being cloned & enqueued from different users basically?

Hi ScantCrab97 , what is the flow you and your colleague follow? Both simply clone and enqueue from the UI but simply use different accounts on the same workspace? Are the queues exactly the same (checking so no different ~/clearml.conf files are used)

And how is the agent configured to authenticate with GitHub?

I am using ssh credentials and my colleague git token

Yes, you are right

ScantCrab97 what authentication mode are you using, what does your colleague use?
