Private DNS Couldn't Connect - ways to troubleshoot?

Hello,

I've had NextDNS up and running for over a year and everything has been working well till this morning. No known changes or updates overnight. Now, when I use the NextDNS's hostname or DNS server IPs, I get a "Private DNS server cannot be accessed" response and internet is blocked. Changing the DNS server to 1.1.1.1 or 8.8.8.8 immediately resolves the issue. This occurs both on Android and on my windows PC. Any ideas what I could check to see why this has now occurred - online or on router (pfsense)? Again, no other updates or changes have occurred. 

 

Thanks in advance for any insight.

    Possibly check DNS lookup for “dns.nextdns.io” ?

       thanks! I'll check that. It did resolve after a number of hours but I'm lost trying to understand why it would randomly stop working.

    Update: The issue seemed to resolve after a number of hours but it is still frustrating to have it stop working for no clear reason. If anybody can help explain why that might happen so I can prevent it in the future, that would be wonderful. Ultimately I had to switch to another DNS resolver for that period of time so I could continue working.
