Bug description

I am trying to upload multiple files bigger than 1GB, but it keeps resulting in an error next to the file mentioning The operation couldn't be completed. (NSFileProviderErrorDomain error -2005.) and I'm not sure if its something on my side or Nextcloud's side.

You can see in the images below that most if not all my files failed to upload because of this error.

Steps to reproduce

1. Upload multiple files over 1GB
2. Wait a few minutes
3. You should see the error next to a file, like I have shown in the image above.

Expected behavior

I should be able to upload multiple files over any file size limit with no issues or errors.

Additional info

I'm using OpenID Connect to log into Nextcloud, and using the Nextcloud AIO image which is why I am not on the latest version of Nextcloud Server. I am curious if it is being limited by both my NEXTCLOUD_UPLOAD_LIMIT which is set to 16G and my NEXTCLOUD_MAX_TIME which is set to 7200.

Let me know if you need any other information!

The chunked upload fails because it does not return an ocId:

{"category":"Item","date":"2026.05.07 20:24:04.608","details":{},"level":"error","message":"Could not upload item with filename: ATM10-Server.tar.gz,\n    received error: 408\n    \n    received ocId: empty"}

This might be related to a chunked upload assembly bug in the Nextcloud sever which I read about recently.

I need time to debug this.
