[Django]-Error H13 on Heroku when uploading images to Django admin with Gunicorn

Heroku web workers time out after 30 seconds if the request cannot be completed by then. You might be getting this error if your upload speeds are really slow right now and it can’t complete the response in 30 seconds. If it’s not your upload speeds, it might be the upload speed between Heroku and S3 since it seems like your uploads are directed there.
