Laravel backup to dropbox not working on production

[schonhose]

Today I updated my laravel install and implemented laravel backup to dropbox using fresh tokens. On my development server this is working fine, the backup is correctly uploaded.

Same setup transfered to the production server, which is actually my hosting company, does not work. Strangely, Storage::disk('dropbox')->put('demo.txt', "Yes, it works!"); does work, and I can also read the file and display the outcome. So I know that the filesystem (with fresh tokens) is actually working.

When running php artisan backup:run the terminal stays on "Copying zip to disk named dropbox" without displaying any errors. However, nothing is uploaded. I cannot seem to find out what is happening, as there is no feedback.

I decided to give webdav a go, and I finally got that to work (the correct folder needs to be made for laravel-backup to upload the file). However, I find it strange that dropbox stopped working. From my logging I could see the last upload was in Nov 2024, but no composer update have been uploaded during that time. Any ideas on how I can debug this further?
