SOS Problem with big file upload

While uploading with uppy to webserver, the upload seems to go on to 100% while in the background it really stops after app. 300MB. Then reaching 100% it restarts from the actually uploaded %. So to upload 1GB it takes 4 times and it restarts after about 25%, 50% and 75% within the same upload, with no user interaction.
Please help!
Uploader code:

    let uppy_source = Uppy.Core({
                    autoRetry: true,
                    retryDelays: [0, 1000, 3000, 5000, 10000],
                    overridePatchMethod: true, // Because production-servers-setup doesn't support PATCH http requests
                    chunkSize: 1000 * 1000, // Bytes
                    restrictions: {
                        maxFileSize: 1024 * 1024 * 1024 * 10,
                        maxNumberOfFiles: 1,
                        minNumberOfFiles: 1,
                        allowedFileTypes: ['image/*', 'video/*', 'application/*', 'application/zip', 'application/x-rar-compressed', 'application/vnd.rar', '.rar', '.zip']
                    }})//application/mxf
                    .use(Uppy.Dashboard, {
                        inline: true,
                        target: '#drag-drop-area-source',
                        resume: true,
                        autoRetry: true,
                    })
                    .use(Uppy.Tus, {
                        endpoint: window.site_url + "/tus/"
                    });

Can you provide any more details?

The best I can do without those details is to send the links to a couple issues on the Uppy and Tus GitHub’s with a similar report
