My Rpi Model 3B+ is connected through my laptop using VNC instead of HDMI and monitor, unfortunately I ran into some problems,I tried making the Rpi Headless by following this video on YT: https://www.youtube.com/watch?v=DkqzLHopaeE&t=56s but it didnt work. So I went back to my laptop, then when reconnected to VNC it says connection refused from the computer, then found a way around from this error by opening Putty and entering my Rpi's IP Address accessing the command shell of Rpi, then by typing vncserver it will then only allow to have the connection. but there were major problems like: 1) trying to open Raspberry Pi Configuration on the Main Menu is not showing and same goes for other Options. 2) Have to open Putty and enter the IP of my Rpi then login then type vncserver to have it working again and again. unlike before i just straight open it on VNC.
Maybe because i think the commands used in that video ovveruled the RPi? It told me to open the crontab etc. it says all in the video. Im really lost now. I have to use a TV/ Monitor again just to open the Raspberry Pi Configuration.
