As expected, this site uses the same Widevine system as Movistar Plus does.
Nv-Authorization which is simply copied from Chrome won't work (= returns a 400 error).

Customized script is needed to automatically finishes all these process just like Movistar Plus do.
PM someone who you trust to do this. Your site is not allowed to be asked for help here since it is a paid service.

I'm wondering if this website use same protection as Movistar Plus ? Did you see in the manifest both NAGRA and PSSH? Is it the same in Movistar Plus's manifest?

Thanks for that snippet code ! I had to deal with WidevinePsshData lib too to generate some PSSH for SFR, wasn't that easy
But here the Nagra PSSH seems to have another function since the widevine one is already here..
I tried making a post request as usual to :

https://195.api-vfp2.ott.kaltura.com/api_v3/service//asset/action/getPlaybackContext

with both and got

{"status":"UNGRANTED_REQUEST","code":400,"errorCode":4018,"message":"Invalid request"}
{"status":"UNGRANTED_REQUEST","code":400,"errorCode":2001,"message":"Invalid request"}

Why do we need it? Isn't the Widevine PSSH enough to generate the Challenge? Both contain the same KeyID and ContentID.
