Need help connecting to VPN inside NetHunter Rootless (Termux)

[kopepoc]

Installed Termux on my Samsung Galaxy S10.
Then NetHunter Rootless (https://www.kali.org/docs/nethunter/nethunter-rootless/#usage).
Then start it from Termux with "nethunter kex". The log is this:

~ $ nethunter kex
vncserver: No matching VNC server running for this user!
vncserver: No matching VNC server running for this user!


NetHunter KeX server sessions:

X DISPLAY # RFB PORT # RFB UNIX PATH PROCESS ID # SERVER
1 5901 14166 Xtigervnc

You can use the KeX client to connect to any of these displays.

Then I open the app NetHunter KeX with those settings and get the error:

Error!

Connection failed.

Any help to fix this?

For some reason some software was missing so didn't work. Fixed it running this script (after cloning the tweakandtools package with git inside Kali):
https://github.com/yadavvivek654/tweakandtools/blob/main/tweakandtools-kex-repair

Very useful software.
