TeamSpeak 3 not working

[Melchett1]

I am failing to get TeamSpeak 3 working.

I have port forwarded the required ports for Teamspeak 3 per the instructions in https://helpforum.sky.com/t5/Broadband-Talk/How-to-set-up-port-forwarding/ba-p/2662260

However, the ports are still not open. I have double checked that my PC firewall allows the permissions.

Additionally, I can log into Teamspeak when using 5g on my phone but not when using wifi.
