(Tight)VNC server at the remote desktop is set up well. This I could verify by connecting to it from my PC (Ubuntu 18.04). But when I try to login to the server from my laptop (Ubuntu 16:04) using Real VNC (client), I get an error message which says:
Unable to connect via my_ip:port: VNC viewer was unable to negotiate a connection with the proxy due to a protocol error
Can anyone help?
Update: I am able to access the remote server using Remmina remote desktop client. The problem with Real VNC still persists.
