UDM Pro Max Install Issue - Error Test Query

Hi all,
I am trying to install ControlD via Automatic installer and when I run the cli command while SSH'd into my Unifi Dream Machine Pro Max I am getting an error.

Command I ran
sh -c 'sh -c "$(curl -sSL https://api.controld.com/dl)" -s ******* forced'

Output:

Hey There.

Reboot UDM PRO and then rerun the installer.
It will work. Just make sure you rerun the script right after the reboot.

Hey! Thanks for your quick reply, I reboot the UDM Pro Max and ran the command and the same error occured.

This error suggests the DNS listener that ctrld spawns is not reachable for some reason, which is quite unusual, but can be caused by conflicting software or firewall rules.

Try starting ctrld manually with: /data/controld/ctrld start --cd RESOLVER_ID_HERE --skip-self-checks

The service will not exit, but you will likely have broken DNS. Perform the troubleshooting guide in this state, as per https://github.com/Control-D-Inc/ctrld/wiki/Troubleshooting-Guide

I went through the troubleshooting steps and even though the last command failed, I noticed I that Endpoint is now reflecting as online, odd but if it works I guess that's good. Eitherway, here are the screenshots of the troubleshooting steps.

netstat -tupln | grep ctrld

dig verify.controld.com @127.0.0.1 -p5354

netstat -tupln | grep ":53\b"

ctrld start --log /tmp/ctrld.log -vv

'/data/controld/ctrld start --cd **** --skip_self_checks'

Few Questions since I moved from AdGuard and NextDNS,
Do I have to re-install after every Unifi update ?

Do I have to re-install after every Unifi update ?

No.

After starting ctrld with --skip_self_check, do dig verify.controld.com run ok?

The i/o timeout means something went wrong and block test query from reaching ctrld listener. But the dig command still run ok, which is weird.

Oh wait, your netstat command shows that there's no listener on port 5354 for ipv4 ...

I reboot'd the UDM and it still functioning well, but I'm not sure what did it? I see the analytics flow but if run the command it'd still fail?
