During the join operation the code at

correctly checks if the returned status code is anything else than 204 and tries to raise an error if so. However it is then ignored by _raise_from_response since it has an additional check for the error code not being 'ok':

I assume it is also the case for the method invalidate(). https://github.com/ammaraskar/pyCraft/blob/ff9a0813b64a0afdf3cd089ad9000350bb4122bc/minecraft/authentication.py#L263-L265

I have not tested it on this method however.
