Raspberry Pi - VNC No Matching Security Types

The problem:

Many VNC clients may not work with the newest security options that are present in the VNC Server that is provided with Raspberry Pi OS ( Rasbian ). You might see an error like this “vnc no matching security types”.

The solution:

The easiest and most secure way to fix this is probably to use the official client from RealVNC. This is what I used. You can find it at RealVNC HERE.

Another option would be do downgrade the security options on the server. I didn’t do this myself but supposedly the following steps should work.

• Edit this file:

/root/.vnc/config.d/vncserver-x11

• Add these lines to the end of the file:

Authentication=VncAuth
Encryption=AlwaysOff
Password=e0fd0472492935da

• Restart the server

• Change t he password like this:

vncpasswd -service
