Remote Desktop cannot connect to the remote computer for one of the following reasons.

Question

Hello World! I currently have a Windows 10 Virtual Machine which had been working normally, but recently had the problem of not allowing remote file connection.

I have already restored a backup before it started failing, but the problem persists.

Here I leave the configured rules hoping you can support me. THANK YOU

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you are unable to RDP to a VM in Azure.

I am uploading a English translated image of the Screenshot you have posted.

The NSG looks good.

• Can you make sure the if the NSG rules attached to the NIC/subnet also allow RDP.
• Which method were you using?
  • Using the IP of the VM
  • or Using the IP of a Load Balancer where the VM is a backend pool
  • or Using an Azure Firewall's IP and DNAT
• Make sure you are RDPing to the correct Public IP of the VM
  • Make sure the Public IP is attached to the targetVM
  • Navigate to the VM and to the NIC from Networking blade
  • And make sure an IP is allocated to the NIC
  • Please share the output (you can redact the Public IP)
• Are you able to RDP from a different VM in the same subnet/Vnet using the private IP of the targetVM?
• Refer : Azure VM cannot connect to another Azure VM in same virtual network
• Run PsPing from the testVM to private IP and from your local machine to the public IP of the VM.
  • Download Psping
  • From local machine, open CMD as admin and navigate to the folder containing psping
  • Run, psping <Public IP of the VM>:3389
  • From the testVM, open CMD as admin and navigate to the folder containing psping
  • Run, psping <Private IP of the VM>:3389
  • And share the output of the above two
• Use IP Flow Verify to check if traffic is allowed or not

Cheers,
