Nextcloud Hub 3 (25.0.2) Upload Issues

I cannot upload files larger than 2mb.

Usecase using the sync tool to upload h265 hevc files from smartphone 7min 47gb automatically. not used as a file storage or anything other than syncing my android smart phones video folder.
Typically modern smart phone produce photos which are 20mb and even that file size wont upload but anything under 2mb works fine.

Host O/S : Proxmox 7.3.4 64bit
LXC O/S : Debian 11 / Ubuntu 20.04 64bit 16gb of ram assigned 4 cores ( i tried both and same issue )
Web Server: Nginx reverse proxy
Database: MariaDB
PHP: 7.4fpm set to use 6gb ram
redis-server: yes with php-redis installed

Nginx upload size set: client_max_body_size 800M;

Result of find -name php.ini

  • ./php/7.4/phpdbg/php.ini - upload_max_filesize = 800M
  • /php/7.4/cli/php.ini - upload_max_filesize = 800M
  • ./php/7.4/fpm/php.ini - upload_max_filesize = 800M

I am at a bit of a loss on what else it can be i have rebooted and restarted services one at a time i have tried without redis. i have 2 other instances on V23 and they work fine i can upload 100gb files no issues. Its just this instance where i wanted to create one so i have a portal for video footage to sync and upload in the background so the files are ready to edit when i get home. i just cannot get files larger than 2mb to upload if anyone has any ideas please share as i am going round in circles on this.

Here is a documentation regarding large uploads:

As you see which components play a role, it is perhaps easier to enable specific logging to see which part fails.
