Hello, dear Nextcloud community!
This is my first post here, so be gentle, senpais. 
Yesterday, I built a small server for my home out of old spare parts I had laying around.
I went ahead, set up and configured Nextcloud (15.0.2), following the documentation and Arch Wiki as reference.
The Problem
Everything seems to be working fine and speedy, except that I’m unable to upload picture files reliably. Sometimes, it works, sometimes not. Most of the time not, espacially when uploading entire folders of pictures.
When uploading, the progress bar appears, indicating the estimated upload time. At first, it uploads just fine, but then it just gets stuck, displaying “x minutes left” (or similar), not uploading any further.
On the other hand: Uploading regular / non-media files seems to work, even in bulk.
I searched the forums and the bugtracker and found several similar entries, but no solution. Anyone got a clue what I should try next?
I cleared the log file and checked if some error pops up when trying to upload. Nothing. Also nothing suspicious in the webserver logs. I also tried disabling all apps, checked the permissions, removed some fstab mount parameters in case something cases trouble, etc.
Overview
- Operating System: Arch Linux
- Webserver: NGINX (1.15.8)
- PHP backend: PHP-FPM (7.3.1)
- Database: MariaDB (10.3.12)
- Caching: Redis (5.0.3) and APCu (5.1.16)
- Data directory moved to a different location

All packages were installed by pacman (or from AUR in case of some PHP modules like imagick).
