Cannot RDP to Azure VM

Question

Cannot RDP to Azure VM

Jevon Davis 141

I have come to realize tat I can no longer remote to my Azure VM. I could do so a day before but the following day I could not. I have tried all the necessary troubleshooting outlined in the RDP troubleshooting docs. I have tried:

Resetting RDP configs
Resetting RDP credentials
Checking resource health
Serial logs
Resetting the NIC
Redeploying the VM I had to restore from a backup which was a week old. I know the problem is with the VM but not sure how I could repair it. I tried to restore from the back up which occurred a day after it started giving issues and it is the same problem. Still cannot RDP so I think that tell me the problem is with the VM. Any solution I could try?

Update: The issue was resolved, detaching the disc and attempting a repair seems to have narrowed it down to a particular VPN software that had taken over the ports for connection. It was uninstalled, the disk reattached and connecting was once more possible

Without properly understanding the issue on the backup, we can't troubleshoot the issue well.
Still, I am thinking an option.

Create a different VM within the same subnet with a similar internal IP range of the problematic VM
Try RDP from the new VM, using internal IP (Make sure that there is no NSG rules set to block the RDP port 3389)
If still RDP is not working, try accessing the the the VM's services, files etc. to see if something can indicate the problem

I had tried this before as there are several VMs in the subnet. Just that is the only one that is not connecting through RDP or SSH

RDP uses to connect Windows VM and SSH is for Linux VMs. Do you know the VM's OS type clearly? The steps provided above are for a windows VM

Yes I am aware of the OS. Can be connected through Bastion for SSH, it is a Windows 10 OS

No, the OS is version is clear. It was bit confused as you indicated that you use SSH
Now, more indications are stated in the last comment that you use a bastion host to connect. Have you checked the page to troubleshoot bastion issues described here: https://learn.microsoft.com/en-us/azure/bastion/troubleshoot

Bastion isn't a standard thing, was trying to use it to troubleshoot but it fails also. The primary connection wasn't Bastion. That was me exploring all possibilities. The primary connection is RDP. This is all bizarre that one day it was good and the other day it just stops responding. I don't know if this helps, I had realized that the VM had shutdown on its own to restart but thought nothing of it. Waking up the following day and seeing that the issue started...I guess that maybe had something to do with it.
