Describe the bug

import asyncio

URL = 'http://your-ip:3000/upload'


async def chunks(data, chunk_size):
    with tqdm.wrapattr(io.BytesIO(data), 'read', total=len(data)) as f:

I am trying to make a CLI client for OpenSpeedTest-Server I am getting same error like this. to reproduce this use our DOCKER IMAGE or Android App. then make a post request to "http://your-ip:3000/upload" issues : For docker image it will only send first chunk for Android app it will throw error like this.

It is working fine when using Electron Apps of OpenSpeedTest-Server (Windows, Mac and Linux GUI Server apps) it uses Express server.

Mobile Apps uses iOnic WebServer, for Android it's NanoHTTP Server and for iOS it is GDC WebServer. for Docker we use Nginx WebServer. Configuration posted on my profile.

To Reproduce

1. Download OpenSpeedTest-Server Android App 2)Run script i posted after changing the IP address to the one shown in the app. 3)Make sure you are making a POST request to http://your-ip/upload
2. Error

Expected behavior

If you run the same script on GUI OpenSpeedTest -Server (Electron Apps) Upload finishes without issue.
