I have two different servers running on different machines and one server sending a .tar file to another, but I am not receiving the whole file only get one chunk of data.

Server 1 : Headers from the server I am sending the file :

Server 2 : Code where I am receiving that file through API

import fs from "fs";
 this.post("/webhook",
 async (req, res) => {
   req.pipe(fs.createWriteStream(`./default.tar.gz`));
   req.on("end", () => {
     // have to update in db that file has been saved
   });
})

Problem: If I run both servers on different machine stream doesn't work and only send one chunk of data however if I run both servers on the same machine it works perfectly fine.
