Error "license - check protobufs" and key solutions

[xxxxxchanchu]

Please help me.

I dumped the CDM and ran WKS-KEYS, but I get an error.

l3.py
PSSH: ...
License URL: ...
unable to parse license - check protobufs

The header and mpd used are as follows.
Can someone lead me to the right key?

headers.py

[Attachment 76695 - Click to enlarge]

[shellcmd]

license token expired. need a fresh license url.

I updated the video and tried to get the header again, but the situation doesn't change.
How large is headers.py?

[shellcmd]

it is empty, so this is enough:

headers = {}
