Question

I tried to connect to a server using the following code:

extends Node

var irc: StreamPeerTCP = StreamPeerTCP.new()
var thread: Thread

func _ready():
	thread = Thread.new()
	thread.start(connect_to_server.bind("irc.libera.chat", "#bottesting", "SparkwavesTestClient"))

func connect_to_server(server: String, channel: String, nickname: String):
	print("Connecting to " + server + ":6667")
	irc.connect_to_host(server, 6667)
	
	while irc.get_status() == StreamPeerTCP.STATUS_CONNECTING:
		pass
		
	print("You will never see this")

The console never prints the last print line, and .get_status() is permanently stuck on StreamPeerTCP.STATUS_CONNECTING. If I do not put it in a thread the entire application freezes instead. I tried connecting using ncat instead, and it connected instantly. It does this no matter what kind of URL I connect to as long as it’s a valid URL, even localhost. An invalid URL exits correctly.

Try putting await get_tree().process_frame in the while loop instead of pass

Your while loop does not allow the StreamPeerTCP to advance it’s own logic, so it will always return the same thing, thus it will halt.

I figured out what to do. The solution is to replace the pass with irc.poll(). That fixes this issue.
