Difficulty setting up Adguard Home

I Have the same trouble here...

I'm trying to figure out what might be going on, as the installation script always used to work correctly—moving dnsmasq to port 54 and assigning port 53 to AdGuard Home—but now I can't complete the setup via the address 192.168.15.1:3000 (using the router's IP, 192.168.15.1, here).

Getting back to the discussion...

Guys, where does AdGuard store its information/settings?

I ask this because:

I don't have AdGuard installed on my system;
I start a fresh installation;
I go to my_router_ip:3000 and nothing works;
I go to my_router_ip:8080, the settings page opens, and I'm able to log in using the root username and the password I had set during previous installations...
I tried using different browsers and their incognito modes, but that didn't yield the desired result.
Based on the above, I believe there might be "lgarbage" data somewhere that wasn't completely cleared during uninstallation, and this is causing issues with the new installation. Therefore, I'd like to remove everything—even if done manually—and start the installation from scratch.

I ran a test in my virtual test environment, and this scenario doesn't occur there.

Guys...

I have several of theses errors in my log...

When installing AdGuard Home, I moved my dnsmasq to port 5353...
How can I resolve this situation?Could you please help me?

Hi Frollic, how are you?

Thanks for trying to help me—I reviewed and redid my configuration, and now everything seems to be working as it should have from the start, though I'm still testing it.

Let's see if I run into anything "abnormal" going forward.

Thanks again!
