My bad I didn't explain what did I do for troubleshooting.

Tried:

Use different wifi (home wifi, office wifi, public wifi)

Switch to different web browsers (chrome, firefox, safari)

System troubleshooting such as... (System, chrome Restart Clear chrome data/cache reinstall chrome, Flushed dns, No firewall, No AV)

Upload with different devices (Mac, iPad, pc, iPhone)

I tried all this on July 14 (Night), July 15 (Morning), July 15 (Evening), and July 16 (Noon).

Haven't tried since then, so I'm gonna try now as well.

Here is a submission from Hitctrl and myself :)
