I have been trying throughout the day to connect to my Windows 10 desktop from my Zorin OS laptop using RDP on Remmina. In my Windows 10 desktop, I have stopped my antivirus firewall as well as disabled the Defender firewall. I also have another laptop running Ubuntu 18.04.4, and from there, I am easily able to connect to Windows 10 in RDP mode using Remmina. However, the same is not true for my Zorin OS machine. I tried removing the freerdp folder by running the following command:
rm -rf ~/.config/freerdp/
However, even after that, when I restart Remmina and try to connect, the problem remains. I'm also not understanding what the difference is between Zorin OS and Ubuntu that it shouldn't connect from the former, but does so from the latter.
