Steps to reproduce

1. Open talk app on android
2. Go on any conversation
3. Upload a large image (like 4MB) and it won't appear or it will mention upload failed

Expected behaviour

Upload the file with no issues, the same as for smaller ones.

Actual behaviour

For small files it works, likely due to a different mechanism. For large uploads the file does not appear on chat, although it exists on the Talk directory and I can normally open it and see through nextcloud files. On iOS there is no issue since it uses a PUT request.
