TheThingsStack V3.8.7 with self-signed certificate -> Forbidden Token exchange refused

@benolayinka, I can’t see any of @TheIronNinja’s config settings in the example ttn-lw-stack-docker.yml file. That file only contains TTN_LW_BLOB_LOCAL_DIRECTORY, TTN_LW_REDIS_ADDRESS, and TTN_LW_IS_DATABASE_URI. @TheIronNinja has specified 7 additional settings in their post, as well as adding port 8885 to the console oauth client registration.
