I'm using dns.mullvad.net and have also tried using dns.quad9.net. The same thing keeps happening over and over. I can't predict what determines whether or not I'll have DNS query issues. Sometimes, it works, sometimes it doesn't. Lately, I've had nothing but issues. It keeps happening and I don't know how to fix it. I've searched through the forum and on the internet and have found nothing regarding my issue. For clarification sake, I am not using a vpn, and I am just using the private dns setting in settings. I have it set to "Private DNS provider hostname" with dns.mullvad.net. Same issues also happen on dns.quad9.net.
