Specify websocket protocol for instances

[veN1337]

Hi,
I'm running Mainsail in a container and specify my remote Moonraker instance in the config.json.
Because the Moonsail container is accessed through a reverse proxy with https, the websocket protocol for the Moonraker instance is automatically assumed as wss://. This is not corrected, because wss:// is not enabled on Moonraker and the connection fails . Due to technical limitations I can not enable wss:// on Moonraker and would like to continue using insecure websocket (ws://). If I turn off https on the reverse proxy, Moonsail assumes ws as protocol and the connection works again.
Is there a way to manually specify the protocol for a Moonraker instance?

No this is not allowed, because this is a browser limitation. So this function is also "hardcoded" in Mainsail. Every browser only allows to connect between the same "secure level" so http websites can only connect to ws sockets and https websites can only connect to wss sockets. So a cross connection is not allowed by the browser itself. So wenn we allow this in Mainsail, you will not be able to connect to your printer with a setup like this.

So you can only host your Mainsail instance without SSL (http) or add a cert to Moonraker and connect via wss.

Oh ok, I wasn't aware of that browser limitation or design/security decision Thanks for explaining :)
