iOS app will not upload in to a folder called Photos

This problem exist on every iPhone we try, if I create a folder called ‘Photos’ we can upload from Firefox no problem but not the mobile apps, any other folder name no problem, no matter if created on the website or app we can upload, just not if the folder is called Photos?
We have a production version on a VPS and a local version for testing, same on both.
I have disabled the photos app, no change.
Ubuntu 20.04 NC 19.0.1
Any ideas?
Thanks all

Hello @HenrysCat ,

welcome to the community of Nextcloud.

You started a topic in support category.

Unfortunately you ignored the template and a lot of information to help you is missing.

Please add all necessary information like webserver type and version, log entries …

Without additional information the community members cannot help you .

Photos is the default folder for automatic upload?
Are you referring to manual or automatic upload?

Which iOS version are you using?
Which app version are you using?

Hi, sorry about that, webserver is Nginx v1.18.0 PHP 7.4.3, /var/log/nextcloug.log is empty, Not using automatic uploads only manual, tested on iPhone SE iOS13.6 and iPhone 7+ iOS13.6, latest app from from app store as downloaded today on both phones.

When trying to upload in to a folder called Photos, the app just freezes, but any other folder name no problem, and this happens on both production VPS and our Hyper V test server.

Just found this under logging from Admin settings.

{“reqId”:“W2RpdtqdQeVIOWf3EcFz”,“level”:3,“time”:“2020-08-13T10:20:05+00:00”,“remoteAddr”:"",“user”:"–",“app”:“PHP”,“method”:"",“url”:"–",“message”:“Trying to access array offset on value of type int at /var/www/nextcloud/lib/private/Files/Node/Node.php#328”,“userAgent”:"–",“version”:“”,“id”:“5f351a5a8965e”}

Which log level are you using in your config.php ?

Any entries in webserver log?

Sorry, we have now destroyed the VPS reinstalled Ubuntu & Nextcloud from scratch and it’s working ok.
