Raffaele Montella - A Signal K server is instal...

A Signal K server is installed here: https://signalk.meteo.uniparthenope.it/ it provides data from a local weather station network. I tried to configure a Data Connection from another Signal K server via WebSocket SSL. The dashboard signals: "This connection is deprecated and must be deleted". Any workaround? How I can connect the server on the boat to a server on the shore to get data?
