Bug description

Since i updated my Nextcloud (docker community image behind Traefik 2 reverse proxy) the upload in the webUI and the client does not work anymore.
A Friend of mine has the same problem and he the default zip downloaded package with nginx on Ubuntu

Errors in the nextcloud admin interface look like this:

• BadRequest Expected filesize of 10485760 bytes but read (from Nextcloud client) and wrote (to Nextcloud storage) 1990656 bytes. Could either be a network problem on the sending side or a problem writing to the storage on the server side.

Here are screenshots from the errors in the browser:

Steps to reproduce

1. Use 28.0.5
2. Upload a File (I used a 2.9 gb file)

Expected behavior

Upload should work

Installation method

Community Docker image

Nextcloud Server version

28

Operating system

502 response code means your webserver timed out, this looks like a setup issue 🤔

Traefik also had an issue and is fixed since
#44113 (comment)

[0verEngineer]

As i said in my issue, a friend of mine who uses a relatively standard way of hosting Nextcloud with nginx has the same issue and it only happens since i updated

[skjnldsv]

@0verEngineer I understand, thanks for replying!
Can you confirm your friend experience the same errors? While the issue might look the same, it might be from different causes :)
