Hello Umer Malik,

Greetings! Welcome to Microsoft Q&A Platform.

I understand that the VM ‘MyVM’ is having trouble reporting the status of its VM agent or extensions and issue with the VM guest agent itself as this error indicates "VMAgentStatusCommunicationError".

You will not be able to uninstall this extension in case the agent itself is not running as uninstall workflow communicates with the guest agent. This extension is used for resetting the password for VM. Here are a few steps you can take to troubleshoot this issue:

Quick troubleshooting steps: Note: After each troubleshooting step, try reconnecting to the VM.

• Reset the SSH configuration.
• Reset the credentials for the user.
• Verify the network security group rules permit SSH traffic.
• Ensure that a Network Security Group rule exists to permit SSH traffic (by default, TCP port 22).
• You cannot use port redirection / mapping without using an Azure load balancer.
• Check the VM resource health.
• Ensure that the VM reports as being healthy.
• If you have boot diagnostics enabled, verify the VM is not reporting boot errors in the logs.
• Restart the VM.
• Redeploy the VM.
