Virtual Machine Scale Sets - Error Installing Microsoft.VisualStudio.Services.TeamServicesAgent

Question

I created virtual machine scale set and i followed the below documentation to configure it as an agent pool in azure devops.

https://learn.microsoft.com/en-us/azure/devops/pipelines/agents/scale-set-agents?view=azure-devops#troubleshooting-issues

After configuring , i cant find the agents under the agent pool created in Devops.

When i checked the instances in VMSS, the instances are update with latest model and they are up and running.On furthur anlaysis I found that there was an issue installing extension for devops on the instance

Below are the logs from the faulty VM
