Hi guys,
I posted yesterday that I couldn't use DTube as I have got millions of error messages while I was uploading the video.
I was making little research and came across of this post from

And hurray, it worked for me! If you are having troubles to upload videos on DTube, try this method. Hopefully it is going to work for you.
