Hi,  
Lately when we are multiple clients (2-3) on our development server, some of us loose some- or ALL -connection towards the Ignition Gateway. This is true with both the Designer, and the vision client.

I get the following errors in the gw log:

1. WebSocket disconnected from session.
2. Websocket connection errored out irreversibly. Closing the session.
3. Websocket connection closed unexpectedly. code=1011, reason=EofException

Below is a screenshot of the logs. Does anyone know where to start troubleshooting with this?

This was related to a IP address conflict on one of the client computers.  
(a local users docker deamon IP pool was conflicting with the server VM docker deamon IP pool)

Is there a solution to this problem? How do I prevent this from happening?

You have to change the default IP ranges used for your local docker, so your container IP addresses does not conflict with your existing IP addresses.

This is done in `daemon.json` . Here is an example of this:
