NIM nemoguard-jailbreak-detect always same response

Suddenly, no matter which obvious jailbreak content I send to it, the API now always responds with the following exact values:

{'jailbreak': False, 'score': -0.567415780013319}

I’ve used the garak attack tool to test this API and, until today, the API always marked DAN type jailbreak attempts as True with a positive floating point number for the score.
