This isn't a Firewalla issue but since the people here are quite knowledgeable hoping someone can guide me to a place that can help. When I click on the link in a Reddit mail notification I get a DNS error – "server not found".

desktop web server can't find click.redditmail.com: NXDOMAIN

MacOS 27.0

Server Not Found

Firefox can’t connect to the server at click.redditmail.com.

Tried Safari, Chrome and Firefox. All give the same error.

I've disabled Control D, MacOS firewall and Little Snitch. Made no difference.

Happens on my Mac connected via Ethernet, WiFi but not when connected to my iPhone when it is connected to the same WiFi network or to cellular.

Love my new Switch X by the way!
