I am not able to connect to a Windows VM from Ubuntu's Remmina. It was all working fine till the day before yesterday but when I tried yesterday- the issue emerged. I asked my colleagues to try connect to Win server from their systems, surprisingly only Windows users are able to connect but none of Ubuntu users. I have found similar posts on SE, but they could not helped me.
[1]. remmina no longer working "cannot connect to RDP server localhost"
[2]. https://unix.stackexchange.com/questions/445613/cant-connect-to-remote-server-using-rdp-remmina-after-upgrade
[3]. Remmina on Ubuntu 20.04 is unable to RDP to Windows 10 Server
This is what I have tried
(1). [2] suggests "updating all freerdp2 libraries (used by remmina) to 2.0.0~git20181120.1 version", but I do not know exactly which ones? I have sudo apt install freerdp2-dev
(2). Removed the ~/.config/freerdp/known_hosts2 file
(3). [3] suggested sudo ip link delete docker0, upon trying I received Cannot find device "docker0"
Any suggestions?
