Hello all !
I’m experiencing an issue where, when I first try to visit a website, the browser shows an error message saying the site doesn’t exist or is down. However, if I refresh the page or wait for a second or two, it eventually loads without any problems.
This issue is also affecting other applications, such as connecting to game servers. Initially, it will say “couldn’t connect,” but then a few seconds later, or after restarting the game, the connection works fine.
My network is setup thus -> ATT Passthrough --> pfSense --> TPLink Managed Switch (1 VLAN)
TPLink Managed Switch -> Deco Mesh Router (192.168.86.0/24)
TPLink Managed Switch -> piHole (10.0.0.10)
I did some digging around and it seems the first query for websites that are cached are very slow. That’s why I keep on getting a “Not Found”
Once they are cached they are fast and thus when I reload the page loads fine.
My current DNS setup is that I use the DNS Resolver in pfSense in “Forward Only” mode. It forwards the request to pihole on a separate VLAN. Pihole uses an unbound server running on the same machine to answer queries.
