Unable to RDP to azure instance - Local Security Authority cannot be contacted

Tags:

azure

Whenever I try to login to my azure instance via RDP I get the following error:

enter image description here

I have tried, rebooting, resetting the RDP settings in the console (configure remote desktop - set expiry for future, etc) and I have also tried logging in with my local admin account (as per the advice here and here) and neither have helped. Before I do something more drastic like try to reset my admin password through powershell or install vnc, I was wondering if anyone had any suggestions. I don't have Azure technical support, so I am not sure if the Microsoft billing support will be much help.

Note: This is a cloud service VM.

How do I fix the Local security Authority Cannot be contacted?

To resolve the issue, change the remote desktop security on the RD server to RDP Security Layer to allow a secure connection using Remote Desktop Protocol encryption.

How do I fix NLA error in Remote Desktop?

If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box. This computer can't connect to the remote computer. Try connecting again, if the problem continues, contact the owner of the remote computer or your network administrator.

I've the same problem when I try connect with RDP to AWS or Azure.

But, I fix the problem when I disabled Anti-virus Bitdefender free.

Verify if you have a Anti-Virus, Proxy, Firewall.

Go to Azure Portal for the service, Configure-> Remote-> set expires on to a future date. In certificate field select Create a new certificate.

Otherwise untick Enable Remote Desktop and apply -> wait until done -> Enable again and that should do it.
