Error: Domain being blocked by AI-Driven Threat Detection.

I just noticed today that one of my domains, which hosts a game in an iframe, is being flagged as a threat and is actually being blocked. I had to add it to my allow list in order to access it.

How and where can I report this? I'd prefer not to disclose the domain here for privacy reasons, but I'd like to know where I can submit a report. I'm quite confident this is a false positive.
