I got HDS link

Fragments are "of course" DRM encrypted

I know the source file (extrapolated), but it's 403 access denied.
Any way to get to it?

Supposed source:
http://static-telemundo.nbcuni.com/M..._5__4000. mp4

(There are files of this video on other CDNs that can be accessed, but I want to access this source file at Akamai - the above link. Akamai is masked by static-telemundo.nbcuni.com but ping leads to a267.b.akamai.net).
