Nice catch!!!! This would have had me on a wild goosechase forever!! There have been no updates to PiHole or CloudFlared and that setup predates my Channels subscription, so I only ensured that PiHole wasn't blocking certain DNS queries, but I never explored CloudFlared!! I'll contact them via Github and inquire about this! Again, thanks for taking a peek at it. New Results below! This is using CloudFlare Public DNS, not the custom CloudFlared DNS.

The Pihole (Local Raspberry Pi) filters all DNS Queries for Ads, Malware, Data Mining, tracking etc. etc. then forwards the allowed queries to a cloudflare upstream server that delivers DNS over HTTPS. In my case 127.0.0.1#5053 Can you PLEASE look into this to see if it's something on the DVR side that can be done so that I can continue to use my current setup? This all worked beautifully together before with no issues. I manually update and manage that server via SSH in a headless setup. I can certainly tell you that other than Pihole admin page updates, nothing concerning cloudflared has changed. @tmm1

That did the trick. All thumbnails were just there when the guide was loaded. Something must have changed w/CloudFlare.

#65

pihole updates gravity every week, by default. Many blocklists include geolocation services.

#66

Yeah, but I checked that yesterday and ruled the PiHole out. No DNS queries coming from Channel's were being touched.

#67

I am running PiHole and haven’t had any of these issues. I’d definitely say CloudFlare is the issue.

The problem appears to be specific to how CloudFlare's DoH works. It's breaking geolocation and causing images to be downloaded from Asia, which is ofcourse quite slow. Using PiHole with a regular DNS upstream should fix the issue.

Switched to Unbound and the issue went away. What a wild goose chase that was.

#70

Hello @tmm1. Yeah, I switched to Unbound, and the issue is no longer present. Thanks for your time and helping me track this down. There were no changes on my side, but they have most likely made changes to the servers they’re using for some reason. Once I read more on it, I quickly realized there’s nothing you can do. I appreciate the time you guys spent looking into this.

@Macnbaish @EdwinG Thanks guys! Your recommendations were spot on and eventually led to the culprit. I removed CloudFlared and installed Unbound in its place and I'm now seeing <1ms response times on cached queries. 2-3ms responses on cold hits! Thanks for chiming in.
