The 2.2.11 release of the flexVDI client for Linux and Live USB includes several stability and performance improvements.
In particular, the WebSocket library NoPoll has been updated to version 0.4.3, reducing its network overhead considerably. In some scenarios, this may result in firewalls or proxy servers dropping connections due to inactivity. For instance, Nginx drops WebSocket connections after 60 seconds of inactivity. This problem can be easily solved setting the KeepAlive property of flexVDI Gateway. It will send a ping message every certain number of seconds, avoiding this kind of disconnections.
