Add-HybridRunbookWorker to Azure Automation not working

You followed the available guide to setup this but the results are not the expected.

Here's a quick troubleshooting sample to help you out.

When executing the powershell command to add the Hybrid Worked, make sure you use the switch -verbose to receive detailed information about the installation.

We confirmed that this particular issue was related with the traffic being blocked on the firewall to the following links\ports:

/en-us/azure/log-analytics/log-analytics-windows-agents#system-requirements-and-required-configuration

After allowing the traffic, success.

Hope this helps!
