TikTok Sign Algorithm General Concept Question

[lalokupfer]

I am trying to run with Frida this example: https://github.com/SebastienWae/tiktok-gorgon-bridge

I managed to do it all and finally run successfully the command:
frida -U com.zhiliaoapp.musically -l C:\Users\WizBoost\Downloads\Tools\compiled.js --runtime=v8
In which I get a good result:
Attaching...
[SM N950N::com.zhiliaoapp.musically]->

But unfortunately I get "unable to connect" when trying to send the POST request:
curl --request POST

I am able to set up a simple node.js express application and connect and send to it the above request, but when attaching it to frida
[frida -U com.zhiliaoapp.musically -l C:\Users\WizBoost\Downloads\Tools\compiled.js --runtime=v8]

For some reason nobody is listening on the port.... 4000
I even tried to compile it with a different port and it doesn't work.
I use windows 10 and the frida server is installed in the Nox Android Emulator.
Any ideas why it doesn't work?
