I am using react on frontend and express on backend.

Here is my code that I use to upload files:

    const formData = new FormData();
    formData.append('file', blob);
    formData.append('title', videoName);

    const request = new XMLHttpRequest();
    request.open('POST', `${process.env.URL}/api/video`); 
    request.withCredentials = true;
    request.setRequestHeader('lang', router.locale as string)
    request.upload.onprogress = e => {
        setUploadProgress(Math.floor((e.loaded / e.total) * 100));
    };
    request.onload = () => {
        const resp = JSON.parse(request.response);
        setRequestErr({
            mess: resp.message, 
            code: resp.statusCode
        })
        resp.statusCode === 401 && logoutUser()
        setIsVideoBeingSent(false);
        setModalType('info')
        
        if(resp.status === 200){
            setModalInfoType('success')
        } else{
            setModalInfoType('fail')
        }
    };

    request.send(formData);

It works perfectly locally, on both smaller and larger files (up to 150mb).

The problem occurs when I try to upload the file to a server hosted on amazon. The 150mb file stops at about 25 percent and does not move further.

I am using express-fileupload with settings:

const fileUpload = require('express-fileupload');

let Options = {
    limits: { fileSize: 200 * 1024 * 1024 },
    useTempFiles: true,
    abortOnLimit: true,
    tempFileDir: './content/tmp/',
    uploadTimeout: 0,
    debug: true,
}

router.post("/", TokenVerify, fileUpload(Options), UploadVideo);

Console in server shows nothing, no errors or other messages. Console in the browser returns only:

POST /api/video net::ERR_CONNECTION_ABORTED

What could be the cause of this?
