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?

Did you try increasing the “maximum concurrent queries” value? Any difference or is the current number the maximum allowed by the router?
-
Just noticed latest MikroTik version 7.8 introduce some DoH fix. Still not sure if the issue is MikroTik and NextDNS?
-
Chris Did you ever figure this out?
-
Rob de Jonge Hi mate, nah. Still experiencing same issue and now when I am experiencing the timeout, webpages doesn't work. Thinking of switching to another provider :(
-
Chris You and me both. Just not sure where to! :)
-
Chris Same problem here.. Is it a known bug? working with other DoH-Providers (working without problems!) :-(
-
Chris ..and as a note: it was running for 2 weeks - untill I switch to the paid version today..
-
Chris What IP adresses are you using for "dns.nextdns.io"?
-
Patrick De Zordo Hi Patrick, find the attached IP's below...
-
Patrick De Zordo The same with me, all started when I switched to paid version.....
-
Chris from which country are you using nextdns?
-
Patrick De Zordo Australia
-
Chris could you try the following IPs?
207.148.84.39, 103.1.213.21 for dns.nextdns.io
-
Patrick De Zordo Thanks Patrick, changed the IP as suggested. Will report back....
-
Patrick De Zordo Still having issues as per the screenshot attached. As highlighted in the screenshot, MikroTik version 7.9 introduced new features in the DNS settings...... any idea/suggestions of the optimal values??
-
Chris we are using the following settings, and we get just 1-5 timouts a day..
it's not perfect, but "ok" for now..
-
Patrick De Zordo Made the changes and timeout increased....... not sure what more I can do
-
Chris
same issued at Viet Nam, did nextdns change something? -
Anh Vu Hey mate, not sure what NEXTDNS did but it has been a nightmare since the error started filing up log file. To make it worse, this is a paid version and nothing official from NEXTDNS staff!!!

Chris
Today, I found reason to make nextdns timeout by enable rule dns in logging. So some device in my home network was tried to connect from their server like bitcoin from china and hongkong. Then I create rule to drop connection from list in firewall then connection timeout reduced.
I'm not good at English, so I hope you guys understand.

Anh Vu yeah, we understand!
Since yesterday we are using "ultralow1" and "ultralow2" server IPs for "dns.nextdns.io".
Here in Italy the 2 IPs we are using: 178.255.155.63 and 192.145.127.148 - for now we have had 12 hours without any "timeout" or "connection error". (ROS 7.9 on x86)
Can you check your "utlralow" servers in your country by opening the following page please?
-
Patrick De Zordo how did you obtain IP addresses for "ultralow1/2"? I have attached screenshot from ping.nextdns.io
-
Anh Vu Nice work mate. Anh Vu I have enable DNS logging and I can only see private IP's and not public IP on my list which if blocked the router would break
-
Chris it (should) be documented somewhere; can't find it right now, but it's really simple:
ultralow1=gsl-adl this will become ipv4-gsl-adl-1.edge.nextdns.io => 116.90.72.196
ultralow2=zetta-adl this will become ipv4-zetta-adl-1.edge.nextdns.io => 119.252.93.133
So just use the 2 IPs for 2 static DNS records for "dns.nextdns.io", and configure DNS parameters as in my screenshots.
Then try to observe if it is working better..?
