File upload problems. Some work, some don't.

[ghost]

Description

Can't upload any file to a channel or private discussion. (both normal and experimental app)
The app will show the usual settings for the upload (name / description). If you hit "upload" it will actually send the file to the server, but when it reaches 100% it will tell you that it failed and you should "Try again". Doing so will show the same error.

Update: If you try to send images, that you've received via whatsapp or downloaded somewhere, it actually suceeds. If you upload camera photos it fails. Downloaded PDFs also work
Tested with an empty whitelist and -1 file size.

Can anyone help me with this? Is there a hard coded size limit or whitelist in the app?

Logs

Unfortunately no relevant logs are generated on the server.
This happens when you access the upload file dialog:

The usual entry like "success=true" or at least some form of feedback is missing though. No error or anything when the file upload fails.

I'm also encountering this bug with server version 2.0.0 and client versions 4.0.2.2087 and 3.5.0 (2074).
I can also confirm that e.g. Whatsapp images are successfully uploaded

The Android app has moved to React Native.

Please see: #2499

And: https://rocket.chat/2019/10/11/moving-mobile-apps-to-react/

Anyone on Android 3.5.x should upgrade to v4.x and follow up in the React Native repo:
