Reviewing

[jykae]

@marla-singer #1701 seems to function right.

However with GPRS presets on I get this kind of situation, spinner spinning and resumable errors to console.

Browser: Chrome 53.0.2785.116 (64-bit)
OS: macOS Sierra 10.12

@jykae Please do screenshot Network tab then you upload file

[marla-singer]

@jykae Which OS and browser do you use?

View with network tab open:

@jykae Well, GPRS presets looks bad for testing feature. File's uploaded too slow. Time is out and connection closes 👎
please test it on "Regular 2G" presets. File will be uploaded ~2min

@marla-singer macOS Sierra is quite new, maybe it's related to Chrome on Sierra, error comes from resumable.js code. Check versions above in previous screenshot.
Maybe someone else could check with Chrome/Chromium, that is not on macOS Sierra.

EDIT: ok, I try out with "Regular 2G".

[jykae]

"Regular 2G" works as expected 👍

@jykae Aha, I think so. When I tested it on Hackintosh with macOS Sierra, i had this problem too. Connection opens only ~6 sec. But I slandered a pirated OS :D

@marla-singer I think we can merge this, if there's still issue let's open new one.
