sockets - Port forwarding to a python UDP server not working

Question

I've a simple UDP python server set up on my computer which I'd like to access from over the internet. I want to open a port and forward data to my python server but I can't get it to open for some reason. I use this site which says the port is closed despite having port forwarded. https://www.yougetsignal.com/tools/open-ports/.

Here's a screenshot of my router settings

I can access the server locally.

import socket
localIP     = "192.168.1.106"
localPort   = 8080
bufferSize  = 1024



msgFromServer       = "Hello UDP Client"

bytesToSend         = str.encode(msgFromServer)
UDPServerSocket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)
UDPServerSocket.bind((localIP, localPort))
print("UDP server up and listening")

while(True):

    bytesAddressPair = UDPServerSocket.recvfrom(bufferSize)

    message = bytesAddressPair[0]

    address = bytesAddressPair[1]

    clientMsg = "Message from Client:{}".format(message)
    clientIP  = "Client IP Address:{}".format(address)

    print(clientMsg)
    print(clientIP)

    UDPServerSocket.sendto(bytesToSend, address)

Website says it doesn't work
