You may need to update your code to work in Godot 4. As per godotengine/godot-docs#6393:

• is_connected_to_host() was removed from StreamPeerTCP and PacketPeerUDP as per [Net] Make TCP poll explicit, drop is_connected_to_host. #59582.
  • get_status() can be used in StreamPeerTCP instead.
  • is_socket_connected() can be used in PacketPeerUDP instead.

Thank you, I'm sorry, I don't think I understand, the linked documentation only references PacketPeerUDP and not UDPServer, should I only be using PacketPeerUDP even though I don't intend to send packets, only receive?

based on that I tried https://docs.godotengine.org/en/latest/classes/class_packetpeerudp.html#class-packetpeerudp-method-wait

extends Node
var socket = PacketPeerUDP.new()

func _ready():
	
	if socket.bind(4592,"*") != OK:
		print("Failed to bind to port 4592")
		return
	else:
		print('started on port 4592')
		
	while socket.wait() == OK:
		var data = socket.get_packet().get_string_from_ascii()
		print(data)
		if data == "end":
			return

and can't receive any packets

documentation has been updated and everything works now, closing, thanks!
