Unleashed 200.19 does DNS lookup of dauth.cloud.ruckuswireless.com every 5 sec.

I run pi-holes. I noticed an uptick in DNS queries at about 6:30am EDT 2026/3/12. I discovered that my Unleashed is looking up this domain name dauth.cloud.ruckuswireless.com every 5 seconds and it caused the uptick. I inspected the pi-hole logs and found that Unleashed looked up this domain every 11 hours (yes, not a typo - eleven, seems unusual) prior to that date and time. 

Why did it start doing this every 5 seconds? I am not using any cloud services. I upgraded to 200.19 from 200.18 about 3 days before it started happening. I haven't changed anything in the setup for quite a long time. The domain is resolved by my DNS successfully and the server responds to pings. I am out of ideas why this is happening. My APs are R750.

Is anybody here? I rebooted my APs and the lookup for that domain is back to every 11 hours. It would have been nice if someone could provide feedback on what happened. I am almost sure it will be back to every 5 seconds in some time.

Hi @Alleprt,
Let me check on this.

Hi,

I have been running the captures for couple hours now and I do not see any dns request to dauth.cloud.ruckuswireless.com.

Could you please let us know the request you see on your side? Probably a screen shot will help.

Hi Sanjay. Thank you for your reply. You need to run captures for at least 11-12 hours to see this query. Before the havoc started, queries to that domain were every 11 hours as I mentioned. Below is a screenshot from the log of my pi-hole. I rebooted my APs around 9:08 on March 16th and after that the queries went back to every 11 hours. But as you can see, before they were every 5 seconds. 

Why would Unleashed try to connect to that domain? I am not using anything cloud. Please re-read my original post on how it all started. I guess it will start querying every 5 seconds in a couple of days again. This had never happened before I updated to 200.19.
