Hi 
We have recently upgraded to Gitlab 15.1, apart of this upgrade required that we upgrade our Kubernetes connection from using the certificate to an agent-based connection.
We are running AWS EKS 1.21
So far we have been able to connect the cluster from the documentation: Sign in · GitLab
When we run a review app pipeline (which is how we previously deployed to the cluster via the certificate method), the pipeline is able to create a deployment in the cluster, but when it tries to pull the image from the gitlab registry it returns the following errors:

I am wondering if there is something I’m missing with the installation for the agent as the agent isn’t able to authenticate back to the internal gitlab registry to pull the image.
Please let me know if you need more information to help!
Thanks
James
