Setting up tcp proxy for the first time, probably misunderstood some concepts

This is my first time using a Proxy to intercept tcp data and I think I misunderstood some concepts and this is why I'm unable to correctly intercept/log packets.
Here is my setup:

1. My application:
   My application is an android app that I run on an Android Studio virtual device. It communicates with a distant server hosted at IP 42.2.2.2.2 on port 2222 (fake ip and port for privacy reasons)

2. My proxy:
   I'm using this proxy: https://github.com/ickerwx/tcpproxy and sending all my traffic that goes to 42.2.2.2.2:2222 to 127.0.0.1:1111 using proxifier. I then launch my proxy using these settings:
   python tcpproxy.py -ti 42.2.2.2.2 -tp 2222-li 127.0.0.1 -lp 1111 -im log -om log -v

Now, here are the results I get in my cmd:

Connection from 127.0.0.1:53333

My application doesn't seem to be able to communicate with its distant server anymore, and I can still see the requests in Wireshark, making me think that the proxy is blocking the packets instead of passing them on to the server. Am I right to assume that ?

What did I misunderstood/set up wrong ?

I'm thanking you for reading up until now and I'm open to any pointer or feedback.
