It could be various things- check your privacy/ management settings for your video, as it might be set to "private," meaning it's not available for public viewing or unlisted. Try to view a full listing of all your videos and see if it's there.
If you still can't find it, try uploading again or rendering locally into a video format, then upload it manually to YouTube.
There's a help article about issues uploading to YouTube you can check out here.
