Hello @sns ,
Thanks for posting your query on Microsoft QnA.
The network connectivity is getting blocked because you have a network security group rule in place that is denying all inbound connections. You will have to add an inbound NSG rule that allows RDP to your VM with a priority lower than that of DenyAllInBound rule. Let's say if you DenyAllInBound rule has a priority 200, your RDP inbound rule must have a priority <200.
Refer to this document : troubleshoot-rdp-nsg-problem.

Hello @sns , Can you try to login to the VM using these credentials via Serial console? This is just to check if the credentials are working or not. If not, then please try to reset password for this user account life and retry. Also in your question I see you have tried to test your connectivity to the VM using network watcher, but for SSH (port 22), whereas you are trying to RDP, which uses separate port (3389 usually if not the port has been changed to a custom port).
Could you please check the above and see if it is working?

Hi @sns , Serial console provides the access to VM's console from the Portal. Please make sure you have EMS enabled in your VM. You will have to go to the serial console option from the VM blade. You will see a SAC prompt, where first you will have to type cmd , press Enter, then type ch -si 1, then again press enter. You will be then prompted to enter username, domain (do not enter anything, simply press enter if you are using local admin account), and password. Post this, you will be able to access the command prompt of your VM remotely. This is to check if you are successfully able to authenticate with your user account.
If at the beginning you do not get a SAC prompt on the serial console, then go to Run command on the VM blade, and hit enter on Enable EMS option and repeat the above steps.

Refer to the Use CMD or Powershell section in this document - serial-console-windows.
