Share file to Nextcloud results in a Connection error

[Zeashh]

⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Use the "Share" button on a file in any app, for instance on a picture in the Gallery
2. Click "Nextcloud"
3. Select the root or any folder
4. Try to upload

Expected behaviour

Uploading a file using the "Share" button should work without the need to go into the app and retry the upload every time

Actual behaviour

File upload fails immediately with the notification "Upload failed - Could not upload FILE_NAME.EXTENSION". Navigating to the Uploads tab in the app shows "Connection error". Clicking the file in this tab makes Nextcloud try to upload again and it succeeds. This behavior is 100% consistent.
