Problem/Motivation

Adguard hassio add-on does not start due to port 53 bind failing

Expected behavior

as i have no other service running using that port the add on should start

There is not much I can do from an add-on perspective. It means you are already running something that takes up that port. Free up the port if you'd like to use AdGuard Home instead.

Hei, Point is that the port was actually not in use as the screenshot suggests… Eventually hassio freed it after a couple of times rebooting… but i have no other service or addon using it. I m pretty sure of that… So i think there maybe is an issue on the hassio level blocking the port… which then affects adguard..

@JanMR21 That makes no sense, as you scan TCP use of port 53, which is not used by DNS.

No matter the case, this message is not provided by the add-on, but by your system that refuses binding. We cannot fix your system, you know best how you configured it. We can't do anything about it.

This has been an ongoing issue for months, if the issue isn't with this addon it is with HassOS so I suppose we should open an issue there. See issue #298
