It seems to be back working again.
I had reported it to Avast. But the blacklist must have gotten removed before he started testing as he couldnt recreate the alert.
It's odd how one.network got on there. I wonder if its a similar name to another malicious website or something.
Anyways, all is good. I can continue to watch the road works around the area.. the modern form of bird watching = road work traffic signs
