Unable to Access VM via SSH After Reboot

Question

After rebooting the VM, access via SSH has been lost. What steps can be taken to resolve this issue?

Answer 1

Hi @Abubakar Ali ,

do you get an error message when you try to connect via SSH?

Maybe this helps to verify SSH : Use the Azure VM Serial Console -> Check that SSH service is running & Check which port SSH is running on

There are more steps described to troubleshoot.

Hi Abubakar Ali,

Thank you for reaching out to the Microsoft Q&A platform.
Based on your question description we understand that you are Unable to Access VM via SSH After Reboot.

In addition to Andreas, please follow the below troubleshot steps:

Reset the SSH configuration and reset the credentials for the user.

Verify the network security group rules permit SSH traffic and role assignment.

Ensure that a Network Security Group rule exists to permit SSH traffic (by default, TCP port 22).

If you are using Microsoft Entra ID to manage SSH logins, the user must be assigned the Virtual Machine Administrator Login or Virtual Machine User Login role on the resource group that contains the VM and its associated resources.

Check the VM resource health and the VM reports as being healthy.

Restart the VM and Redeploy the VM.
