ErrImagePull when running Airflow on K8s

We run Airflow on K8s on DigitalOcean using Helm Chart. Tasks are written using airflow.contrib.operators.kubernetes_pod_operator.KubernetesPodOperator. On a regular basis we see that pods are failing with the following messages (but the issue is not constant, so the majority of time it works fine):

We are using KubernetesExecutor.

Helm Chart info - airflow-stable/airflow version 7.16.0

That are most likely just DigitalOcean Registry issues I suggest to try dockerhub
