HTTPS support is broken for a printer farm

[RomRider]

Describe the bug:
I'm running Mainsail in https and in docker.
In this setup, multiple printer setup is not possible as the browser complains that the websocket needs to be opened using the wss protocol.

Note: I'm also running my Moonraker instances behind HTTPS.

This line always returns ws://:

mainsail/src/store/farm/printer/getters.ts

Line 11 in 5d2400c

return state.socket.protocol+'://'+state.socket.hostname+':'+state.socket.port+'/websocket'

Expected behavior:
I can use the printer farm feature while running Mainsail and Moonraker behind HTTPS
