Unable to upload files

I am unable to upload files.

Steps to reproduce the issue:

  1. Click on assets and upload
  2. select a file

Expected Behaviour:
File uploads and is ready for usage

Actual Behaviour
I see the snackbar informing me that upload began, but it is not shown after 20 minutes (5MB image, fast connection)

Only occurs on http connection and on https it just works using select image component --> choose image --> upload --> …

Note if you are over 10 MB

Refresh page after asset uploading.

Makeroid apps can have a size of round about 20MB
