I cannot get the key with the l3.py script using the headers extracted from chrome dev tools. I am using the wks-key script from https://forum.videohelp.com/threads/411509-WKS_KEYS-updated-protobuf-to-version-4
My cdm should be working as I can get keys from other sites.

The PSSH and headers should be correct as I can get the keys with the PSSH and headers from https://cdrm-project.com/.

Are there any tweaks that are needed to the l3 script to get the keys from dmm tv?

maybe you need, custom data, x auth token
or something like that in your headers

This is the license request extracted from curl converter. I should have the headers correct. I saw a long string of non-base64 encoded string (probably byte) in the data that is posted to the license request server. Is it anything about it?
