I am using Nextcloud 15.
It’s great and amazing, but I am facing issues with images Upload.
When uploading a file a message appears: “An unknown error has occurred”.
I can upload other filetypes like mp3 pr txt or pdf.
But not png or jpg.
I tried doing it via android app but it did not upload images neither.
There is no message in the logs.
How may I debug this issue?
Using CentOs 7 and PHP 7.02
