Connecting to REST API, 400 error : "invalid_token". Error_description: "No valid bindings were found for organization and technical account combination"

[Russell_TST]

I have been trying to access the REST API for user management using Python. All the credentials i have used for creating my JWT and access request token are correct and my cert is not expired. The "invalid_token" error i thought to be an issue with the formatting of the JWT, but the description says other wise making me believe something is wrong with my credentials for the API integration. I cant find anyone with a similar issue as mine. Is there an issue with my org id and tech account? Thanks for the help!
