Excuse me, your links are indeed fine when loaded from a video player. That's odd, I don't recall akamai refusing to serve the hls manifest to browsers before. I wonder why they started doing that...
Did you feed them to a player? They're not intended to be clicked on a browser,
I get the access denied error too if I click on either, but they play fine if I load them within a player.
For example on VLC, select from menu: Media->Open Network stream, then paste one of the links and hit Play. Unless they're restricted in your area they should play fine.
Multiple launch issues including fueling and a an apparent "interflange crack" which doesn't sound good.
The loading of propellant was delayed by about an hour because of passing storms and the danger of lightning. Then a leak popped up in a hydrogen fuel line. That was resolved, and both propellant tanks have been filled in the rocket's core stage. Engineers are now investigating two other issues. The first is a possible “crack in an intertank flange.”
