Prerequisites

Platform (OS and CPU architecture)

Windows, AMD64 (aka x86_64)

Installation

GitHub releases or script from README

Setup

On a router, DHCP is handled by the router

AdGuard Home version

Action

Turning on "use AdGuard browsing security web service" breaks AdGuard home and DNS stops routing turning it back off everything works as normal.

Expected result

DNS to route

Actual result

It doesn't

Additional information and/or screenshots

I have it running on a Lenovo mini computer running Windows 11. The host computer is plugged into my firewall and the IP of the AdGuard DNS server is set on the LAN.
Adguard home is running as a service and works fine until I turn on "security web service" then DNS stops routing till I either turn that setting off or disable Adgaurd in general.

AdGuard support asked me to reach out here. If I need to share more information let me know. Thanks everyone!

This seems to be fixed after I just updated to Version: v0.108.0-b.54 that was just released 4 hours ago. I'll keep monitoring it and update everyone if it becomes an issue again. Thanks!

I'm having the issue again. I even tried reinstalling Adguardhome on a new device and other versions. It quits working only when I enable security web service.

Thanks!

I have it running as a service on a Windows 11 box. Version:

Network settings of the host:

Network settings of my Unifi firewall:

And my config (the .yaml file)

If I need to take any logs or share anything else to diagnose this let me know!

It also looks like others have reported the same issue:

And another #5213 (comment)

So I may have figured it out based on this comment: #3029 (comment) I couldn't access that page so I tried turning random security services off on my Unifi firewall. I turned off "country restrictions" and it seemingly started working again as well did turning on security web service started working again. I'll continue to monitor.

I did a reverse DNS lookup and it looks like https://dns.adguard.com/ is based out of Cyprus. I honestly don't remember if I had that on my block list. But I'll continue testing.

Thanks!

Update: I turned back on my country restrictions on my firewall > blocked Cyprus and lo and behold. Quit working again. Firewall doing as it should :)

Update - so far after turning off my restriction on Cypress from my firewall everything is working great!
