See the more detailed browser compatibility wiki page.
Unless you are using a VNC server with support for WebSockets connections (such as x11vnc/libvncserver, QEMU, or PocketVNC), you need to use a WebSockets to TCP socket proxy. There is a python proxy included ('websockify').
-
Use the launch script to start a mini-webserver and the WebSockets proxy (websockify). The
--vncoption is used to specify the location of a running VNC server:./utils/launch.sh --vnc localhost:5901 -
Point your browser to the cut-and-paste URL that is output by the launch script. Enter a password if the VNC server has one configured. Hit the Connect button and enjoy!
