[Bug] Large File Uploads Freezing Midway

[SSoft7]

Current Behavior

Large file uploads are getting stuck midway (at a random percentage), preventing the upload from completing successfully (Tested using 5GB+ files).

Expected Behavior

Large file uploads should complete without interruption, progressing smoothly from start to finish

Steps To Reproduce

1. Generate a large file - head -c 6G /dev/urandom > random_file.bin . I would prefer to use a regular file instead.
2. Visit AzureSpeedTest.com for large file upload test.
3. Select and upload the file. The progress indicator will get stuck at a random percentage. In my case it was always getting stuck at 37%

N.A

Anything else?

I rebuilt the image using your ubuntu baseimage and the upload just works fine.

I'm creating this issue since the other issues #75 and #113 are almost 3-5 years old and received no resolution. I think this app should be rebased to debian/ubuntu if no solution can be found. You can also offer a debian/ubuntu version separately if that is an option.

The problem comes from Firefox itself. I was able to reproduce with a VM running Alpine Linux.
I created https://gitlab.alpinelinux.org/alpine/aports/-/issues/17011 with the hope to get some traction.

The problem might not be related to the file size, but with the upload service itself. File upload gets stuck with azurespeed.com, but the same file can be successfully uploaded on filebin.net.

I think different sites handle uploads differently. Filebin is working for me as well but I checked with mediafire.com and it failed.
