Listening to TCP [53] is not working

[zzecool]

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)

Linux, AMD64 (aka x86_64)

Installation

Docker

Setup

On one machine

AdGuard Home version

Version: v0.107.48

Action

In my network im intercepting all the TCP and UDP requests and reidirect them to the Adguard DNS.
This works fine for the UDP but fails on the TCP.

Some applications have hardcoded DNS and when those requests done in TCP Adguard failed to proccess them and application hangs or cant provide data.

For example

An application running in android is making a hardcoded DNS TCP Request to google 8.8.8.8:53

Im redirecting the requests to adguardhome DNS server like i do for UDP

Yet the server doesnt respond back.

This has been happened in previous version as mentioned at: [ Listening to TCP is mandatory in some cases ] #521

Expected result

Adguard should respond to TCP DNS Requests

Actual result

No DNS replies

Additional information and/or screenshots

No response

@zzecool @sweetpants if you use the previous version, does it still happen?

[sweetpants]

Have not tried that yet. I'm running in docker, have to get my hands on older images

Going back to 0.107.25 solved the issue for me.

I've just updatated the AdGuard, then clicked on disable for 1 hour, and after 1 hour I couldn't navigate anymore
tried to restart the service, and the machine but it didn't solved ...

Hi @notjulian, unfortunately that's not enough information for me to reproduce the issue. I would need to know how you have AdGuard Home setup, and where the issue is happening so I can try reproduce the issue.

Just install v0.107.48 and try to make a TCP DNS request.
