[Maxw2191]

This is the video link

https://www.nbc.com/the-kelly-clarkson-show/video/sydney-sweeney-luna-blaise-the-doobi...ers/9000307656

I followed normal process using https://cdrm-project.com/

PSSH:

AAAAV3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADcSEGzNN8 dOukCwmupQhzwyE9IaC2J1eWRybWtleW9zIhBszTfHTrpAsJrq UIc8MhPSSOPclZsG

Lic Url:

https://drmproxy.digitalsvc.apps.nbcuni.com/drm-proxy/license/widevine?time=1750141953...a9b&device=web

and It gave me this key:

6ccd37c74eba40b09aea50873c3213d2:202536a6c693f81b7 d7d66de6ffa7900

but when I use it to decrypt the video it fails to do so.

So can anyone help me getting the real key and explain to me what I did wrong
