Pardon me, thisis complicated for me to understand 
So, basically the workaround is to run these commands one by-one from this thread:
/ip dns
set allow-remote-requests=yes doh-max-concurrent-queries=100 \
doh-max-server-connections=20 doh-timeout=6s servers=1.1.1.1,1.0.0.1 \
use-doh-server=https://1.1.1.1/dns-query verify-doh-cert=yes
