My university offers remote connection to Library PCs. Here is a list of RDP files they offer. The RDP files works seamlessly with Windows 10. But in Ubuntu LTS 20.04, it does not work.
Here, I enter my credentials and domain(although not required).

Then it says,
I don't know what the issue is. Please don't ask me to use VNC or ssh. Nor ask me to change router settings. These PCs are in my University library.
