Script for updating the game that demonstrates the windows-only HTTPRequest problem I'm having

update.gd

extends HTTPRequest

func _ready():
    connect("request_completed", self, "_request_completed")
    # Check if we need an update
    request("http://cosinegaming.com/static/vanagloria/version.json")

func _request_completed(result, response_code, headers, body):
    if result != RESULT_SUCCESS:
        print("ERROR: COULD NOT UPDATE. RESULT #" + str(result))
        completed()
        return
    # Just checking if we need an update
    var server = JSON.parse(body.get_string_from_utf8()).result
    # 0.0.0 -> Update-shell application, needs more resources
    if server.version == util.version and util.version != "0.0.0":
        completed()
    else:
        # Update the game, irrelevant for this example
        pass

func completed():
    get_tree().change_scene("res://scenes/lobby.tscn")
