I started receiving 401 errors when using Media DB to pull board game info from BGG. Tried outside of Obsidian and same result. Turns out BoardGameGeek is rolling out registration requirements to access its API

https://boardgamegeek.com/using_the_xml_api

We are in the process of requiring registration and authorization for use of the XML API. If you are an existing XML API user, in order to prevent a disruption in your service, we recommend that you register and add authorization to all of your XML API requests.

Media DB will need to add a user assignable BoardGameGeek key same as OMDb, Moby, etc.
