Pywidevine Obtaining Decryption Key Issue 469 Client Error: Unknown for url

[doganjr]

Hello Folks,

I was trying to obtain decryption key for a Widevine video

When I tried it a couple of weeks ago, it was working fine. But, now, I keep getting error message as follows:

b'<error>\n  <code>3003</code>\n  <az_err>1250</az_err>\n  <message>tv3 sts end point denied authorization</message>\n</error>\n'
Traceback (most recent call last):
  File "/Users/******/get_key.py", line 124, in <module>
    licence.raise_for_status()
  File "/opt/anaconda3/envs/req/lib/python3.10/site-packages/requests/models.py", line 1021, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 469 Client Error: Unknown for url: https://ottapp-appgw-amp.nba.com/v1/client/get-widevine-license?ownerUid=azuki&mediaId=NBA_endeavor-0021300008-a_PACKAGE_Jitp_Reach_HD&sessionId=3955dfd8-c81e-4f0d-9165-aeff25677ac3&is_dvr=false

I am using the CDM that I created by using Android Studio, also sending the correct headers to obtain the key(Otherwise it produces bad request error message).

As I want to emphasize, It was working fine a couple weeks ago.

I could not find any post at the forum that focuses the mentioned issue. Anyone can help me about this? I am happy to give detailed info and share the scripts.

Thank you in advance!

No need for detailed info. Video URL?

Sorry for the late response.

Actually, I used the same code and infos(PSSH, links, etc.) after some time, miraculously, I obtained the key. Then, could not replicate the error.

I was watching and trying to download the stream when I faced the error message. It has a very slim chance but maybe that was the issue.

If I encounter with the same error. I will revoke the post.

Thanks!
