Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 20.0.5): 25.0.1
Operating system and version (eg, Ubuntu 20.04): Ubuntu 18.04.6 LTS
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.54
PHP version (eg, 7.4): PHP 7.4.32
nextcloud Liquid for iOS 4.5.6.4

The issue you are facing:
When auto uploading to a remote storage from Nexcloud ios, I get the err 500 Internal server error.
Still, one copy of the file is uploaded to the auto upload destination.
Also “manual” upload to remote storage fails in the same manner.
If I do a manual upload to a folder on local disk (on nexcloud server) I have no problem.
I have done no changes exept auto upgrade on my Ios-phone (13) and manual upgrade of nextcloud.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Set auto upload folder to one on a remote storage
  2. auto or manually upload a file to that folder.

It looks like this is an issue when uploading images to remote storage using the web interface too.

And it gives me the following error:

getimagesizefromstring(): Argument #1 ($string) must be of type string, bool given

The same problem here with 25.0.4 and uploading images from Android device with the app “folder sync”:

With version 24.x there was no problems.
