Since this error is not giving any details about the issue, we can try to troubleshoot the issue by checking the logs of the Azure Container Instances. When you have a misbehaving container in Azure Container Instances, start by viewing its logs with az container logs, and stream its standard out and standard error with az container attach. You can also view logs and events for container instances in the Azure portal, or send log and event data for container groups to Azure Monitor logs. If your container fails to deploy successfully, review the diagnostic information provided by the Azure Container Instances resource provider. To view the events for your container, run the az container show command:
az container show --resource-group myResourceGroup --name mycontainer
