[Dlive] DLive Upload problems

Hi,
I just wanted to upload a 750 Mbytes MP4 640x480p Video on DLive.io
but it always stops the upload at about 85 %.

I have been using the latest Firefox browser and when I put ( drop) the video into the browser
or into Chrome it also plays very smoothly and has no problems, so FireFox and Chrome can play it...

So should I better use Chrome for uploading the videos or is there any other problem right now
with DLive ?

P.S. Sempervideo has put out an interesting help video how to speed up Videouploads
to DTube, but I guess this only works on DTube and not on DLive.
See here:
at youtube go to /watch?v=QugAaVu44l0

I also want to use DLive for 2 reasons:

1. They don´t take a share of your revenues.
2. You can use Animated GIF Animations as the Preview Thumbnails which is a really great feature of the DLive platform.

So do you have any idea what I can do to speedup the upload and complete it , also with Firefox as this is my main
browser ?

Many thanks in advance.

Regards, Stefan.
