@xentrk said in Intermittently losing DNS: @naskar Yes, Cloudflare was the other DNS we tested with and it had no issues like Quad 9. It seems to play better. Just note that the Cloudflare help site does not support DNSSEC and will fail the DoT test if you have DNSSEC turned on. I changed to Cloudfare and have DNSSEC enabled and it seems to be working. But after going to your link I realized that DoT wasn't working. After turning it off DoT works. Is DNSSSEC not important? Is it ok to not use it? Or are you just saying leave DNSSEC on and ignore what the says about DoT?
