Help with large files upload

Is there any general rule to get Nextcloud to upload large files?

I’m using autoupload camera roll and currently I’ve got 10 videos (all of them >300MB) uploading at the same time, but as soon as they finish an error gets triggered. Could this lead to the Upload File error?

It would probably help if you post the error.

There shouldn’t be any problem with a 300 MB file. Some people do have issues with much larger files (2 GB, 10 GB) where some changes to PHP need to be made.
