Looks like everything was getting flagged by the Anti-Malware filter.

it brought down the whole network till I turned off filtering. I changed the DNS to a public DOH server in my router for now.

It's not a good idea to use the malware/security filtering anyway as it adds significant latency to requests.

You'd be better off using an active and maintained malware blocklist instead

I thought that's what it was referring to, the Anti Malware list here that has 25k entries.

Ah ok. So it was a list.

There must have been an errant entry in that list that was black-holing everything then.
