I have inserted flashed SD with raspbian - installed tightvncserver and was able to connect using Remmina(VNC & RDP) via IP address. But now when I try to connect using VNC, I get
Unable to connect to VNC server
and RDP gives
Unable to establish a connection to RDP server
Tried with other application Remote Desktop Viewer and it gives
Connection to host was closed
I had executed some commands (sudo apt-get dist-upgrade) in Rpi3. Now I have no access to Rpi3 to check wheather VNC is disabled. How can I resolve this issue?
