Okay my video uploaded, the trick is:

1. Time (highest possibility): trying to upload at 3:15 AM (my current timezone) so less traffic
2. Install IPFS, been trying to "IPFS init" and "IPFS daemon" on my machine, idk it currently effective or not
3. Been using direct connection before I'm using privoxy for everything.
