DNS stop working

Prerequisites

I have checked the Wiki and Discussions and found no answer
I have searched other issues and found no duplicates
I want to report a bug and not ask a question or ask for help
I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)

Platform (OS and CPU architecture)

FreeBSD, ARM64

Installation

GitHub releases or script from README

Setup

On a router, DHCP is handled by the router

AdGuard Home version

v0.107.45

Action

Replace the following command with the one you're calling or a
description of the failing action:

If the protection is on, there is no output:
nslookup -debug -type=a 'www.example.com' $SERVER_IP
;; connection timed out; no servers could be reached

I have to disable the protection:

nslookup -debug -type=a 'www.example.com' $SERVER_IP
Server: $SERVER_IP
Address: $SERVER_IP#53

QUESTIONS:
    www.example.com, type = A, class = IN
ANSWERS:
->  www.example.com
    internet address = 93.184.216.34
    ttl = 16986
AUTHORITY RECORDS:
ADDITIONAL RECORDS:

Non-authoritative answer:
Name: www.example.com
Address: 93.184.216.34

Expected result

I update to v0.107.45, after few days, it suddenly stop works. I didn't change anything.

Actual result

I have disable the protection, then it will work, otherwise, the DNS failed. and there a lot of error log in the router:

Additional information and/or screenshots

No response

I just noticed that I set "Use AdGuard browsing security web service", I have to turn it off. Looks like the AdGuard DNS server has issue now.

I don't have nor had the "Use AdGuard browsing security web service" enabled.
It SEEMS ok now, but it is intermittent. AT some point it seems to go into se 'dns storm' with hundreds of entries with timeouts similar to Xliangs post. I enabled SSL now and waiting for it to go wrong again, or maybe it helped.
When i previously had it and 'fixed it' with a reboot it took more than a day to occur again. So i can't relay tell yet if my change fixed it.

When it previously went wrong i saw:

I rebooted multiple time, the router, restart the AdguardHome service. But it still happened. Now, I disabled the "Use AdGuard browsing security web service". Then, there will no DNS proxy, and the issue haven't happened for few days. The issue just started from Last weekend about Saturday night.

I have same thing happening to me after the update, server just randomly crash, stoping and restarting the service doesn't do anything only full reboot of the machine in my case.

Since updating to v0.107.45 AdGuard home is blocking multiple services and websites.
I am running it on home assistant OS. A full reboot helps for a brief period of time.

I also tried to disable all the blocklist, but this does not help. AdGuard keeps blocking traffic even when protection is disabled.

Same for me.
Using dnsmasq add-on for now.

Same. Not sure if OP uses HomeAssistant though. I do. Had to shut down AdGuard add-on.

This just started happening to me. I've made no changes to my config. I have one instance running on my Synology NAS, and one instance running as a Home Assistant add-on. Both are exhibiting the same behavior. Both are running v0.107.46.

I've tried restarting the containers, as well as rebooting the host hardware. Neither resolves the issue.

To restore internet, I've just pointed my router at other DNS servers.

edit :

new logs, as you can see there is no 1.1.1.2 in my config it is because it is the dns by default when adguard wants to resolve PTR zone

Hi all, I have been facing these issues for a few weeks now, extremely frustrating for me and my family.

Everything works as expected until suddently, the following repeatedly fills my logs:

2024/07/18 13:15:26.289149 [error] dnsproxy: https://family.adguard-dns.com:443/dns-query: response received over tcp: "requesting https://family.adguard-dns.com:443/dns-query: Get "https://family.adguard-dns.com:443/dns-query?dns=AAABAAABAAAAAAAABDJhZGMEYjYyOAJzYgNkbnMHYWRndWFyZANjb20AABAAAQ\": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)"

It will resolve itself at some point, and we many not see it until a few days later. When it happens I have to jump into my router to change the DNS servers.

I have been using AdguardHome for years, does anyone know what is causing it? I tried downgrading to v0.107.50 but obviously this seems to be an issue with their servers....

There's several issues here.

Requests to family.adguard-dns.com are for the "browsing security web service" option. This adds extra latency to DNS queries, and queries appear to totally fail when this web service is down. You can disable that in the AdGuard Home settings:

I created a separate issue with more details about that: #7175

Failing requests to other servers could mean that your internet is flaky, or that that DNS server is down. You can minimize the impact of unavailable upstream DNS servers by making sure you have multiple upstreams (e.g both Quad9 and Cloudflare) and are using the "Parallel requests" option:

that is simply not true. there is clearly an issue in respecting the settings.

I have "browsing security web service" disabled (since i first installed adguard), as most of the other users with problems in this issue.

I have multiple upstream DNS servers and "Parallel requests" enabled.

The issue is real, its not just bad settings.

family.adguard-dns.com is used as a hashsum provider for checking domain names in both Browsing Security and Parental Control features. Without access to it, AGH cannot check the queries, and thus rejects them all. This is a choice we've made, because the alternative—ignoring the failures and skipping the filtering—potentially exposes children to 18+ content and people to scammy websites, and that's not what we want.

@ainar-g This should be configurable in the UI.

@rursache - If you're still seeing failed requests to family.adguard-dns.com even if browsing security and parental control are disabled, that's not good. The request in your error message:

https://family.adguard-dns.com/dns-query?dns=AAABAAABAAAAAAAABDY3MDkENTE5ZAQ3MWI0AnNiA2RucwdhZGd1YXJkA2NvbQAAEAAB

Is a request to the browsing security service. It's a DNS over HTTPS (DoH) lookup for a subdomain of sb.dns.adguard.com, which is the domain used for "safe browsing" (which I assume is the same thing as "browsing security", since I don't see "browsing security" mentioned in code):

AdGuardHome/internal/home/home.go

Lines 360 to 362 in cdf970f

    
           sbService                 = "safe browsing" 
        
           defaultSafeBrowsingServer = `https://family.adguard-dns.com/dns-query` 
        
           sbTXTSuffix               = `sb.dns.adguard.com.`

Hi all,

AdGuard Home runs at home on a rpi 3 for years now, dhcp server sends his IP as dns servers to every client connexion.

Before blaming AdGuard or upstream DNS : I had EXACTLY similar problem, only first upstream DNS seemed unreachable (down, no ping, not possible to resolve nslookup queries). Others upstream dns where ok to answer queries from local (AdGuard) ssh session with nslookup, but distant clients could not resolve anything.

Problem went away after rebooting this **** TP-Link Deco X50-5G...

Regards,

Christophe.
