DNS-over-TLS break down after some period.

I configure the router to use my own DOT server. The server was all good but maybe a little bit laggy.
The ns lookup was fine at first but broke down after some period. And recovered after a

service restart_dnsmasq

.
Also I'm using dnsmasq.conf.add to add some exceptions for domains.
Maybe it is because of the lag?

Thank you.

It depends on how big is your custom host file... if it's too big, yeah, you'll experience some nslookup lag; for example, mine is around 2mb and dnsmasq runs smoothly.

Mine is about 2mb too. Also confirmed it's not related to the dnsmasq config, since I changed DOT server to quad9 and worked flawlessly.
