Ok, thanks for looking at it jfb.
I just thought it was odd that (from what I remember) the space was all white initially and then now it's getting the "Webpage not availabe" message. And the fact that a couple other people I know didn't have that issue.
I also saw this post from a few weeks ago: https://discourse.pi-hole.net/t/pi-hole-not-blocking-ads/16700/51 and thought it might be related to that fact that I do have "1.1.1.1" in as my secondary DNS on my router. But I guess if it was using the secondary DNS then the ad would actually show up.
I'll keep an eye on it. But if things look good w/ the debug, then I'm probably good.
Thanks again!!!
