Response 401 on search methods

[ARWishere]

I've been using the search methods and it appears that there's an issue with them that generates a 401 unauthorized response rather than a 200, which now leaves an empty list as the output rather than the data I'm attempting to collect. It was working properly for me a few days ago, but as of the past 2 days I've been unable to use search or any of the api methods reliant on it.
