I have a VM in which I installed the VNC server (TightVNC) using the link : https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04

It is installed successfully and I can see the port 5901 running

/etc/tigervnc$ netstat -tulpn

Now from my local machine, I tried to do the port binding to my local from VM (as per the link https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04)

ssh -L 5901:127.0.0.1:5901 -C -N -l test 172.1.1.1

In my local machine, I able to see the port is binded to 5901

/etc/guacamole$ fuser 5901/tcp
5901/tcp: 22049

Now when I try to take the VNC connection using 127.0.0.1:5901, It promopts for VM's password and shows only the blank page.

Could someone help me with this?

Thanks,
Hari

edit your ~/.vnc/xstartup file thus:

#!/bin/sh

startxfce4 &

I had the same problem and this solved it

For reference i got it from here:

You can also try killing and restarting your VNC server

kill $(pgrep Xvnc)
vncserver

Are you trying to VNC from the local machine to the local machine? I am assuming just for testing correct?

If you are not getting a rejection, at least it should be talking to the service.
