Slow DNS after 22.05

In drilling down to where the log errors are coming from, they are part of a firewall alias list used in a single f/w rule which is disabled.
My new question is why the alias being resolved used while the test rule I use the alias in, isn't being used at all.
I assume it's to support dynamic rules which may activate at any time. I removed the FQDN names from the aliases to remove them from generating log errors.
-
It happened again. DNS forwarding off and DNS 'died' within 24 hours in a way which mostly affects CDN content (i.e. YouTube). Nothing interesting in the logs.
Enabling DNS forwarding apparently solves the problem. pfBlocker-devel doesn't seem to be part of the issue (yet).

And what specific did not resolve? Did you do a dig from your client, did you do a dig +trace to see where the resolving was failing?
When you have a dns problem, you need to troubleshoot what exactly is failing.. Like your above entries - that just do not resolve, issue with the parent dns, etc.
-
@johnpoz Can you recommend a log level setting other than Level 3 to catch the failures?
-
@lohphat log might not catch the failure.. Depending on what the failure is - getting back a nx isn't a failure, etc.
What specific fqdn did not resolve - what did you get back from unbound, was it refused was it nx, was it a timeout?
Saying dns didn't work is like telling the mechanic your car is broke. Without details - have no clue to what is wrong or could be wrong.
You can for sure up the log level - also you can have it log queries and replies with
log-queries: yes
log-replies: yesIn the option box, etc.
But some actual details what you specific asked for, what was the response? And then doing a dig +trace is prob going to tell you more of what is failing then in the log..

That's the problem, I don't have a specific FQDN but I have cases where YT thumbnails don't load in a browser on my PC or iPad or on my Roku on my TV -- other similar sites which use distributed content like linkedin.com also fail at the same time. Since the content is embedded, getting the FQDN is more of a challenge.
You can for sure up the log level - also you can have it log queries and replies with

Thanks! Will try this.
But some actual details what you specific asked for, what was the response? And then doing a dig +trace is prob going to tell you more of what is failing then in the log..
Once I can do that I will.

Here we go!
One second duckduckgo.com is resolved and the SAME second it's not.
Note: Not in forwarding mode.

e.g. YT is now failing but only on some FQDNs -- enough to break the UI and prevent thumbnails from loading.

So figure out why servfail - you sure your dns not being intercepted and you failing dnssec?
I am having zero issues resolving that, and your trace for example looks fine.
I would sniff to find out why our having issues.. So you query that directly and you get back servfail - what does unbound show for its cache that - ask it how it would look it up, etc..

Well, this failure mode is intermittent -- it hits then resolves, then his again later, rinse, repeat. It doesn't happen in DNS Forward mode. So I'm guessing whatever it is, is happening in the local cache.
The failure mode affects different devices on different internal networks which are of different architectures: Win11, iPad OS, Roku, Android.
The behavior started after the 22.05 update almost immediately. No other changes other than the base image were made.
The following advanced options are set (and were set in 22.01):
- Prefetch DNS Key Support
- Harden DNSSEC Data
- Keep Probing
- Experimental Bit 0x20 Support
When things start failing again, I'll post the deeper query results.

@lohphat said in Slow DNS after 22.05:
My new question is why the alias being resolved used while the test rule I use the alias in, isn't being used at all.
??
The Alias is defined.
So it get resolved regularly.
An alias can be used not only in a firewall rule, but also some where else.
Or even not used at all : as long as it is defined, it get resolved.No "help me" PM's please. Use the forum, the community will thank you.
Edit : and where are the logs ?? -

@lohphat said in Slow DNS after 22.05:
DNS forwarding and DNSSEC enabled:
That is never a good idea, if your going to forward where you forward either does dnssec or it doesn't you asking for it does nothing - other than problematic.
Interesting side-effect if DNSSEC is disabled, I get a warning if I try to change the Advanced Settings:
The following input errors were detected: Harden DNSSEC Data option can only be enabled if DNSSEC support is enabled.Another example of where info text could be clearer when there are inter-dependencies of settings. I want DNSSEC, but it's not needed if you're forwarding, but then the setting on another page is dependent on it. I didn't get a warning that it was set when I disabled DNSSEC on the main page. Confusing.
Also: The setting default should be included in each setting text so that as you're tweaking over time, knowing the default setting is helpful to return settings to original.

@gertjan But that behavior is not obvious.
Getting DNS lookup failures in the log took me a while to trace where I had those references. I had long forgotten the alias I had created to test a f/w rule for DNS blocking.
