Ngrok tunnel to a Fadecandy server

[medium blue]

I'm trying to connect to a Fadecandy server running on a Raspberry Pi.

I set up two ngrok tunnels one for the www interface one for a Websocket. Fadecandy is listening on port 7890 and so I run ngrok http 7890

I copied ngrok url to my javascript so the line reads now 

var socket = new WebSocket('ws://d952ded366a7.ngrok.io');

When I run it Fadecandy quits immediately with:

WARN: Unknown client spec version 0 double free or corruption (out) Aborted

Is it possible to connect to the Fadecandy server remotely? If so, what am I doing wrong?

Look at your fadecandy config.  By default he server only listens on the loop back interface.

Thank you. Would you be so kind to give me more details. What do I change exactly? It's my first time using Fadecandy.

It's exactly the config I have. The server seems to connect for a second and then quits with the error above. 

Would appreciate any other suggestions.

Its the listen part you want to change from 127.0.0.1 to null, like this. This is in the config.json file.

{
    "listen": [null, 7890],
    "verbose": true,

    "color": {
        "gamma": 2.5,
        "whitepoint": [1.0, 1.0, 1.0]
    },

    "devices": [
        {

Yes, I'm running html examples locally without any problem.

Did you try to use the exampels from here https://github.com/scanlime/fadecandy/blob/master/doc/fc_protocol_websocket.md#connecting without any tunneling?
