[Sonoff relay]device update failed as Web socket is not open - try again after a few seconds at default

I installed homebridge on a raspberry pi 4 and I have the problem described in the title. I mention that it is Sonoff equipment (relay, temperature sensor) that are not in the same network as my system and are on different accounts in other networks. On the Ewilink application I can manage them (start/stop) but in Homebridge they only appear with the last status seen after restarting the plugin. When I try to switch from the application I get the message "[ [Ventilatoare Et2] device update failed as Web socket is not open - try again after a few seconds at default.sendUpdate (file:///var/lib/homebridge/node_modules/homebridge-ewelink/lib/connection/ws.js:345:13)."
