I did "dnsmasq disable" and chose do use Ad-blocking.
Now I can't SSH into my router anymore. putty window is black and then says it's time out.
Any suggestions?

Edit:
I managed to SSH into my router with my android phone.

Edit2:
After rebooting my PC, I also could SSH into my router again.

Edit3:
I see a lot of these "some IP.in-addr.arpa." entries in logging:
What are these?

I'm using unbound (with dnsmasq) since its release on the forum. I keep it up-to-date with both @Martineau and Entware's developments.
Until a while ago it ran for several days/weeks without issues.
Over the past few days I see that it resets itself every few hours - the equivalent of
Code: 
rs nocache
After that it rebuilds the cache quite fast and works well; for a few hours.
I tried to compare the reset time with running cron jobs - not even close. Sometimes it happens at night when the network is as idle as it gets. Also, tried disabling the VPN client - no change.
Here is my configuration:
Code:

Any suggestions on troubleshooting steps?

If its just been happening over the last few days there is the possibility its due to vunerabilities in unbound which have been recently patched.... if your unbound isn't at version 1.10.1 then you should upgrade it via entware.

If your Unbound is the latest and greatest , can you share any syslog or unbound logs that may help figure this out?
 
Must to admire

...nothing gets restored from '/opt/share/unbound/configs/cache.txt' - it all starts from zero and builds up pretty fast.
 
Is it possible to implement some ip addresses (192.168.1.107-108) from other dns servers on DOT which contains the parental control?
 
Finally got around to playing with dnsmasq disable command. Not quite sure about having a one time import, but will see.

I do have some entires that look like this:
85511 xx:xx:xx:xx:xx:xx 192.168.x.xxx * *


These end up creating a *.<domain> mapping inside unbound. Anyone else see that?

Did you previously use the 'dnsmasq disable' command?, i.e. the conversion possibly encountered/created an invalid directive.

You can either rename '/opt/share/unbound/configs/unbound.conf.localhosts' or use option '2/z' to completely uninstall unbound (including '/opt/share/unbound/configs/') ; then reinstall.

You can either use
Code: 
dig +trace addgadgets.com

dig addgadgets.com SOA

dig addgadgets.com NS
or unbound_manager to generate a clickable URL to generate a detailed graphical report of the failure.
Code: 
[Enter] Leave Advanced Tools Menu

A:Option ==> dnssec addgadgets.com

Click https://dnsviz.net/d/addgadgets.com/dnssec/ to view DNSSEC Authentication Chain
to prove that that the SERVFAIL answer tells you there's an issue reaching the DNS server for that domain, or that it isn't set up properly.

Can you not access the menu to issue the '2/z' command to uninstall unbound?

If not try
Code: 
sh /jffs/addons/unbound/unbound_manager.sh uninstall
then retry the unbound install.

Had the same issue, but it's easy to fix, just uninstall the adserver in cli-menu and everything is good again or comment it in the unbound.conf, but it's easier to uninstall the adserver. The issue appears because adserver is enabled by default.

After reinstalling Unbound with DNSmasq running I still don't see any stats going.

Code:

Summary: Cache Hits success=0.00%

So I tried the test proposed some pages before and as you see, after starting Unbound, the lines stopped before tha LAST line as posted by @Martineau

Code: 
keytruda@RT-AC68U_WHITE-FFE8:/tmp/home/root# unbound -dd -v

Jul 05 11:10:23 unbound[15613:0] info: start of service (unbound 1.10.1).

Unboud installed with default .conf file. More in the ipleak test page I see the DNS address of Quad9 as it is specified in the WAN page. So what I'm missing?
