Hi Guys,

I get with all browsers (Chrome, Firefox Safari ...) again and again a "lost connection" internal and external devices.  
Cache of all browsers were emptied.  
The sys.log, with the setting "trace", i will not find any errors.  
Vers. 2.9.5 works without problems.  
Version\> = 2.9.6 I get the "Lost Connection"

Maybe someone has a solution.

You need to give us more to go on. I assume the version you refer to is for Dashboard.

Node and npm versions, Node-RED version.

You also need to check both the Node-RED log AND your browsers console.

Hardware Odroid XU4  
Chromium vers.48 is still running kioskmode in lightdm with AutoCacheCleaner and is linking to [https://127.0.0.1/ui](https://127.0.0.1/ui).  
Connected via HDMI so i can see the Node-Red Ui with connection lost.  
The Odroid have his own network to connect to his Clients and he connected to the www only via openvpn over  
my openvpn-server to another Server with the hivemq-MQT-Server.

Not sure what is going on. If you use a Chromium based browser such as Chrome or (as I use) Vivaldi, you can get a much better view of what is happening with websockets.

By going to the network tab, reloading then clicking on the line that includes `?EIO=3&transport=websocket`, you will see something like this:

Which shows you the frames being received by the websocket connection. The above example is a simple Dashboard that is updated every 10 seconds.

Note that I'm using the latest beta here. The data for the chart is a random number \*100.

BTW, it is helpful to wrap log output with triple back-ticks as it is a lot easier to read.

Not sure I can help much really. It sounds like you are using something as a web proxy? Perhaps that isn't helping?
