+#### Azure Instance Metadata Service (IMDS) connectivity
+
+Azure Site Recovery mobility agent uses [Azure Instance Metadata Service (IMDS)](../virtual-machines/instance-metadata-service.md) to get virtual machine security type. Communications between VM and IMDS never leaves the host. Ensure that you bypass the IP  `169.254.169.254` when using any proxies.

 ### Verify VM certificates
 
 Check that the VMs have the latest root certificates. Otherwise, the VM can't be registered with Site Recovery because of security constraints.
