AWS broken pipe error when uploading files bigger than 1 MB - django

Question

I am a django newbie, and I inherited a django back-end with little documentation. I am making a request to said server, which is hosted on AWS. To store the files in the request we use S3.
I have found nothing on the django code that limits the size of the file uploads, and I suspect it may be AWS closing the connection because of file size.
This is the code I use, and below the error I get whenever the total size of the files is over 1 MB:
import requests
json_dict = {'key_1':'value_1','video':video,'image':,image}
requests.post('https://api.test.whatever.io/v1/register', json=dict_reg)
video is a video file ('.mov','.avi','.mp4',etc) with base64 encoding, and image is an image file ('.jpg','.png') with base64 encoding.
And this is the trace I get, ONLY when the total size is over 1 MB:
/usr/local/lib/python2.7/dist-
packages/requests/packages/urllib3/util/ssl_.py:132: InsecurePlatfo

raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', error(32,
'Broken pipe'))
As mentioned previously, I have not found anywhere in the django code a limit to the file size, any hints where I should be looking at?
I also did not find anything on the AWS S3 policy.

Answer 1

Assuming you have a Nginx to reverse proxy your HTTP requests? if yes check this link.
Also see the value set for the below value in settings for the Upload Handlers in django
FILE_UPLOAD_MAX_MEMORY_SIZE

Answer 2

In the end it was the nginx configuration. changing the variable client_max_body_size in the nginx.conffile from 1M to 2M did the trick.
