I tried to upload your file from our own network and everything gone fine (see on your dashboard).
Can you try again to upload from your own network ? Just add another small project (less than 1.5GB : free space quota) in order to test the upload or delete the one I upload on your interface to try again with the same project and see what happen.

I cannot reproduce your timeout bug with a worst connection than yours (16Mb upload).
Is there any timeout setted on your router ?

You can try your app on Furioos before trying again the upload if you wanna improve 😉

Waiting for your answer to fix that issue.
Have a nice day.
