Seeing errors when uploading multiple image files via AutoUpload from client

ℹ️ Support
1

Nextcloud version (eg, 12.0.2): 13.0.5 (many versions previously tested)
Operating system and version (eg, Ubuntu 17.04): QNAP NAS (many versions previously tested)
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.34 (many versions previously tested)
PHP version (eg, 7.1): 7.2.11 (many versions previously tested)

The issue you are facing:
When I perform file uploads, often (always?) from iOS client (many versions previously tested) various errors occur and interrupt the uploads. If I keep refreshing the client, they eventually will complete. Sometimes I have to manually force an upload to retry.

Is this the first time you’ve seen this error? (Y/N): No, this has been happening for years.

Steps to replicate it:

  1. Take multiple photos or make multiple screenshots.
  2. Open iOS client and watch the destination folder where the auto-uploads go.
  3. Note the many different errors which occur indicate server unreachable or timed out.

The output of your Nextcloud log in Admin > Logging:

Nothing about failed uploads is appearing in my Nextcloud or Apache logs.
