I have been experiencing several errors on MikroTik router RB5009 as shown in the attached photos. I have included my router DNS configuration if anyone is able to assist?

Just noticed latest MikroTik version 7.8 introduce some DoH fix. Still not sure if the issue is MikroTik and NextDNS?

  Chris this can be DoH issued on your mikrotik. This certificate's broken. You can try to delete it from System > Certificates.
  
  Also, no more DoH issues on my home network since I blocked all unauthorized IPs from China and HongKong. I'm very happy now :)
  
  I'm using 2 ultralow server and zepto-sin

It's really frustrating.. we are now also (again) having outages.. 🤔

Why ist no NextDNS Staff reading this posts? 😥

Actually trying with this settings, and it's "better" than before, but not good at all...

  Ronnie Barnett Gidday mate, does NEXTDNS support the use of Google DNS DOH servers? How about certificates, are they included by default on MikroTik routers?
