What AddOn is making all these DNS queries?

1

I really hope someone can help me with a problem I’m having.

I’m trying to setup a RPi4 with hassio (docker) as a home surveillance station using the MotionEye AddOn. I also have it for some other controls (lights and such). I have setup duckdns to be able to access home assistant via e.g. my phone, which works great.

However for some time I have noticed that something in the setup kills my router.
I know it’s the Pi, because when I remove it from the network everything runs stable. When I plug it in, after a few hours/days the network dies.

Everytime the network drops the logs in my asus router says “maximum number of concurrent dns queries reached (max 150)”.

Therefore I thought I’d try to log the DNS queries from hassio to see if I can detect what is making these queries. From what I understand of others having the same issue, 150 concurrent DNS queries is an insane amount and should not happen.

I have tried to look for guides on this, but I can’t seem to find anything useful.
Is this the way to go about my problem? If so, could someone please provide the steps needed (i.e. which addons do I need or where should I look to find the information)?
I’ve tried looking into the DNS logs of hassio from the supervisor, but there are no timestamps there, so it does not provide much info.

Any help would be greatly appreciated!

Is it an MDNS request? you can check using wireshark.

I’ve had a problem with MDNS requests flooding my network and killing my wifi router.

Thanks for answering!
I have only used Wireshark a few times and then to check the PC I was currently working at.
Can I use Wireshark on the PC connected to the same network (wifi) and still see the traffic to and from the Pi (wired)? Or do I need to run it on the Pi?
What should I be looking for in the logs?

Did you find a solution? Same thing started for me after the HassOS update to 5.8. I added the Google Public DNS address today. Maybe that fixes it.
