title: Microsoft Integration Runtime losing Authentication Key on Azure VM
body: <p>I currently have an Azure Virtual Machine that is running Windows Server 2019 Datacenter that I use as a connection point for Azure Data Factory. The Integration Runtime works and so do the pipelines that utilize it.</p>
  <p>The issue arises when the Virtual Machine is shut down at night and started back up in the morning using Runbooks. <a href="https://i.stack.imgur.com/oAMvY.png" rel="nofollow noreferrer">Screenshot</a>. &quot;The Authentication Key is invalid or empty. Specify a valid Authentication Key from the portal&quot;</p>
  <p>This does not always happen. The Integration Runtime can work for a few days and then it stops with the error above. It seems like the only solution is to re-install the Integration Runtime and re-do the linked services in Azure Data Factory.</p>
  <p>I have spent some time trying to figure out what could be causing this error and it seems a little weird that it can work for several days before the error comes up. Has anyone else encountered a similar issue?</p>
