Nextcloud version (eg, 12.0.2): 15.0.7
Operating system and version (eg, Ubuntu 17.04): raspbian (latest) kernel 4.14.98-v7+

The issue you are facing:
While trying to upload a file through nextcloud app on android (v3.6.0) the upload doesn’t start.

When I check the nextcloud.log file all I can see related to this is
“HEAD /remote.php/webdav/20171102-AH%20(53).pdf HTTP/1.0” 302 0 “-” “Mozilla/5.0 (Android) ownCloud-android/3.6.0”

My nextcloud server is behind a reverse proxy but have not encountered issues regarding this before.

When I do the upload through a webbrowser from my desktop it works instantly.

When I restart the php-fpm service the file seems to be uploaded anyhow .

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Upload file through android nextcloud
  2. Status on Android stays at 0%

I can confirm similar behaviour with Nextcloud 16.0.1, Php 7.3, and version 3.6.2 of the Android app.

When I upload a file through the app (picture, text, whatever) it sits in the Current section of the Uploads page. The app indicates that it is “Uploading…” but makes no progress and it is not present in the files webapp (checked from another computer). However, when I ssh into the server that nextcloud is running on and restart php (i.e., systemctl restart php7.3-fpm.service), that is when it becomes available.

I fixed it in my setup. Apparently supplying a custom 404 page in nginx.conf caused the issue. I commented out the line:

error_page 404 = /404.html;

and now everything works. The solution is taken from here:

It does seem odd that I cannot supply a custom 404 page, though.

Confirm that, removed the 404 page and now the upload is working. Not expected that.
