Sonic Pi won't play sound from remote python script

Question

I am using Sonic Pi 3.3.1 on my Windows PC and a Python script(Python3.7.2) on my raspberry pi(Raspbian Buster) that detects distance from an HC-SR04-Ultrasonic Sensor .The program then creates a tune with a pitch that ranges higher if the object is further away ,this tune is then sent over OSC to Sonic Pi. External OSC is enabled on my windows PC. I also checked the Port and ip addresses, and they are correct.

I have tested my circuit extensively and I can confidently say this isn't the source of the problem, and that I added it for documentation purposes only at the bottom of my post for anyone who is interrested ,so I will move on.

My Python code:

from gpiozero import DistanceSensor
from time import sleep
from pythonosc import osc_message_builder
from pythonosc import udp_client
sensor = DistanceSensor(echo=17, trigger=4)
sender = udp_client.SimpleUDPClient('10.0.0.119', 4560)
while True:
    pitch = round(sensor.distance * 100 + 30)
    print(pitch)
    sender.send_message('/play_this', pitch)
    sleep(0.1)

Output:

The problem doesn't seem to be my python code as it logs the correct values and successfully sends the pitch so once again I will move on.

My sonic Pi code:

live_loop :listen do
  use_real_time
  note = sync "/osc/play_this"
  play note[0]
end

Output:

Sonic Pi log's the notes correctly but doesn't play it and this so the data is being received but isn't being played so the problem is most likely how I am trying to play the note but I can't find the correct way to do this

I then Tried this, to test if sonic pi installed correctly and is able to play sound:

live_loop :foo do
  play 60
  sleep 1
end

Sonic Pi did play a sound so I can rule out a defective installation where sound is not installed properly

My Circuit:

The Vcc pin on the HC-SR04-Ultrasonic Sensor is connected to the 5V power supply on the raspberry pi, then the Trig pin is connected to the 4th GPIO connector on the board the echo pin is then connected to the 17th GPIO connector between a voltage divider consisting of a 330 ohm resistor and a 470 ohm resistor Wich protects the raspberry from a full 5V

My circuit looks like:

you need to use the cue path as seen in the cue log. So sync /osc:10.0.0.80:56505/play_this. This should have popped up in the autocomplete after the first message was received by Sonic Pi from your Python script.

If you want your sync to work regardless of where the message came from you can use the * sync /osc*/play_this.
