Azure VM Remote desktop stopped working

[Steven Parsons]

HI,
My Azure VM is no longer allowing me to connect using remote desktop. I receive error message "RDP disconnected! 4 An internal error has occurred."
I've run through all the suggested the steps on this page https://docs.microsoft.com/en-us/azure/virtual-machines/windows/troubleshoot-rdp-connection, and none of them fixed the issue. The Azure VM Resource health is fine, and the VM itself is running.

Does anyone have any other ideas on how I can get this resolved?

did you make any change to DNS?

[#3]

No, I haven't made any changes to the VMs DNS, or the Virtual Subnet. I also have another Azure VM in the same subnet that I can still connect to so I don't think its network related.

[#4]

do you get the internal error after entering credentials?

if so did you do any security or certificate change?

[#5]

Here you can find several articles on resetting different VM configurations:

Is it a Domain joined VM or workgroup VM ?

@Kent Gaardmand In our case this was caused by TLS 1.1 being enabled and TLS 1.2 and TLS 1.3 being disabled. After using File -> Connect Network Registry from another PC we were able to edit the registry of the affected VM and enabling TLS 1.2 and TLS 1.2.
