Godot Version

Godot-Stable-4.5.1

Question

I’m trying to use a self-signed certificate for a Secure WebSocket server on my local network. How can I use the certificate with Godot? I need it to be using WSS in order for some devices (such as many android devices) to connect.

If Godot is your client you can specify unsafe TLS clients for the various websocket types, typically the second parameter

##### Direct web socket peer
var ws := WebSocketPeer.new()
var ws_tls_option := TLSOptions.client_unsafe() # only use for debug! should accept self-signed

var err := ws.connect_to_url(server_host, ws_tls_option)
if err != OK:
	push_error("Failed to attempt connecting to web socket url, ", error_string(err))

##### High level multiplayer peer
var ws_peer := WebSocketMultiplayerPeer.new()
var ws_tls_option := TLSOptions.client_unsafe()

var err := ws_peer.create_client(server_host, ws_tls_option)
if err != OK:
	push_error("Failed to attempt connecting to web socket url, ", error_string(err))
else:
	multiplayer.multiplayer_peer = ws_peer

Thanks! You’re a lifesaver. On a related note, do you know any way to do something similar for HTTPS?

HTTPClient has TLS options on connect_to_host, 3rd agument

HTTPRequest has a method to set TLS options set_tls_options

That did the trick! Thank you!
