Hi @Payal Patil,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

It looks like you're encountering an issue with the Azure Site Recovery (ASR) extension on your Linux VM. Here are some steps you can follow to resolve the issue and restart the extension:

1.Restart the ASR Extension:

• Connect to your VM using SSH.
• Run the following command to restart the ASR extension:

sudo systemctl restart walinuxagent

2.Ensure that your VM has proper network connectivity to the Azure Site Recovery service. Check if the required outbound URLs and IP ranges are accessible

• Ensure the VM has outbound connectivity to the necessary ASR endpoints. Specifically, verify:
  • Port 443 is open.
  • ASR service URLs like hypervrecoverymanager.windowsazure.com are accessible.

4.Restart the VM:

• Sometimes, a simple VM restart can resolve the issue. You can restart the VM from the Azure portal or using the following command:

sudo reboot

5.Restart the ASR Extension

To restart the ASR extension, you need to manually remove and re-enable the extension:

a. Uninstall the ASR extension:

1. Go to the Azure portal and navigate to your VM.
2. In the left-hand menu, go to Settings > Extensions + applications.
3. Locate the ASR extension (it may be named something like VmAgent.AzureBackupLinuxExt
4. Select it and choose Uninstall.

b. Reinstall the ASR extension:

1. Navigate to your Recovery Services Vault in the Azure portal.
2. Under Protected Items, locate the affected VM.
3. Select Replicated Items and click on the affected VM.
4. In the Compute and Network settings, Use the Re-sync or Repair option to attempt automatic resolution. This will reinstall the ASR extension.
