```

There are no messages in `dmesg` regarding the interface, or anything network-related.

The `/run/waydroid-lxc` directory is 777 permissioned and empty.

I have `dnscrypt-proxy` running on port 53, but it's complaining about a pidfile, not the TCP socket. I also tried to relaunch Waydroid container and session with `dnscrypt-proxy` stopped.

I tried to run `dnsmasq` standalone from a `root` shell, with the following command:
```
dnsmasq -x /run/waydroid-lxc/dnsmasq.pid
```
It didn't work, and failed with the same error message as is in the log. It started successfully when the pidfile was not specified (it was created at the default location `/run/dnsmasq.pid`).
