Hello,
I’m currently using Router OS v7.4 with hAP ac2.
I use the following configuration for IP/DNS, which was working fine on the previous version of Router OS. (v7.3.x)
/ip dns
set allow-remote-requests=yes max-concurrent-queries=50 query-server-timeout=\
10s query-total-timeout=1m servers=\
8.8.8.8,1.1.1.1,2001:4860:4860::8888,2606:4700:4700::1111 use-doh-server=\
https://dns.google/dns-query verify-doh-cert=yes
However after upgrading to v7.4, I got an error “DoH server connection error: Invalid argument” on every DNS queries.
After removing the “use-doh-server” setting, the DNS resolution works fine.
