DNS requests to update.qnap.com at approximate 10 minute intervals

Running Technitium DNS and see request from update.qnap.com in log approximately every 10 minutes. The device is a TS-251 with both ethernet ports bonded. It is used for file storage and a repository for Macrium backups. I back the NAS up via HBS 3 to a USB drive on the last day of the month. Any explanations for this behavior and/or solutions/work arounds? Firmware is QTS 5.29.3499 Build 20260514. Thank you.

Could be all sorts of things, is NCSI (online check) enabled?

Interesting. How often do you check for updates?

I run Pi-Hole on my TS-873A and other than requests for some QCenter addresses at MyQnapCloud.com (I run QCenter on the NAS), I see nothing to Qnap itself…

I run a pi-hole too and have 4 NAS’s on my local network. The top 5 “allowed” on my network are all QNAP. The S3 Amazon one is all coming from NAS local ip’s. I don’t use Amazon for anything.

The S3 Amazon is Amazon cloud services. You likely are using an S3 backup of some sort to some service that utilizes Amazon infrastructure. I think QNAP may use it for some of theirs and lots of other services use it too.

I don’t use Amazon anything and all the requests link back to local ip’s of my QNAP’s. I know what S3 is.

Firmware updates are set to check daily and automatically install

I do not see anyplace in Control panel to check NCSI

see here

Thanks for your help with this. I made the change per the instructions, but still get the ping to update.qnap.com every 10 minutes

And update checks are disabled?

Yes. I used the instructions you sent and verified the feature was off.

No I mean firmware update checks

I have them set to notify me, do not automatically update.

But even to notify it has to externally check if they exist.

I get that, but if it is set to check once daily at 4:00 AM, why would it need to ping DNS every 10 minutes 24/7?

That would be a question for a ticket, maybe

Agreed. I think it is time to open one for this. Thanks for your help.
