Unable to download courses on mobile app

[Nik S]

I have installed moodle on my machine.
Setup Django server.
Created an app using oppia mobile code.

I had created a course on moodle and uploaded it to Django server. Now in mobile app, I can see the course that I uploaded but when I try to download it is throwing an error: Error downloading media, Please try again after sometime.

When I try to debug, I see that I am getting end of parse stream error. But when I embed the course as a part of apk, I can open the course.

I would like you to know what is causing this issue and how to fix it??

Are you hosting this in the cloud? could you please send me the link to the oppia server or send me the zip file of the course.
