Description

Hello! This is an amazing project and I admire it!
I faced some problem. I have a server with a white static IP address (for example, X) on which the rttys server is located. I also have several hosts in a private local network behind NAT (for example, 192.168. Y.Y), which are connected to rttys on X. From a third-party PC, I can go to X and access the terminal, everything works well. However, when I click "access devise's web" and enter the port of any service on the final rtty client, I can only view pages with http/https. If a websocket connection is required on the target page, it cannot be established on the proxy page. How to fix this behavior? I would like to be able to connect via X to Y and use websocket.
