Some further information on identifying this issue.

On doing a netstat on the kodi server you can see that the port is only LISTENING locally (or not at all if remote control is off even for this system):
redacted@redacted:~$ netstat -nlut | grep :9090
tcp        0      0 127.0.0.1:9090          0.0.0.0:*               LISTEN     
tcp6       0      0 ::1:9090                :::*                    LISTEN     

But after enabling settings→services→control→Allow remote control from applications on other systems, the LISTEN port shows open to all:
redacted@redacted:~$ netstat -nlut | grep :9090
tcp        0      0 0.0.0.0:9090            0.0.0.0:*               LISTEN     
tcp6       0      0 :::9090                 :::*                    LISTEN

I run into the same problem and could solve it.

Make sure that your firewall is allowing incoming traffic for the EventServer listening on the UDP port 9777 (this is the default port as seen in your 'guisettings.xml' file in 'userdata' folder). See https://kodi.wiki/view/EventServer#Event...ventServer

Make sure that your firewall is allowing incoming traffic for the JSON-RPC API listening on the TCP port 9090 by default. See https://kodi.wiki/view/JSON-RPC_API#WebSocket
If you ever changed this port in your 'advancedsettings.xml' file in 'userdata' folder (see https://kodi.wiki/view/Advancedsettings.xml#jsonrpc), then you also have to give the same value to 'socketsPort:' on line 31 at this time in the file 'kodi-webinterface.js' located in '/usr/share/kodi/addons/webinterface.default/js/' for Linux. Note that this file may be replaced and your change erased in case of Kodi update.

Sorry but recently i have start to obtain this errors when open the Chorus2 from my PC using PC.

I have try to understand how i need to enable or disable........ read the comment #12 report as solution but i don't understand. I have set the port for WEBSERVER to 80 so from my pc i need simply to open 192.168.1.4 (ip of my pi2 on my home network) to open chorus2.
But it's simply unusable because i obtain this error appears on bottom right corner most frequently.

From kodi settings....... i need only to leave activated one of two option and not both option (things default setting) ?? How i need to do to fix this issue ?

And exactly what error is this?

oh.. it's appears "lost websocket" and i need manually to refresh page on pc browser because chorus become unresponsive...

I had this issue too. I enabled "Allow remote control from applications on other systems" and changed websocket port to 9090. The error is gone.
