Not able to establish a connection to RDP server anymore - Check "Security Protocol Negotation"

Problem Description

I use Remmina to connect to a RDP server for years. One day, IT staff do an update on the server or something like that, since I'm not able to connect anymore : Can't establish a connection to RDP server - Check "Security Protocol Negotation"

When I use Windows in VirtualBox to connect the RDP server with Windows tool, that's work but I prefer Remmina.

What is the expected correct behavior?

Establish a connection to RDP without error
