I installed nextdns on my main router, and use an Archer AX73 as wifi access point. I noticed in NextDNS that the router accesses some sites like Reddit, Yahoo, Amazon, Google and Ebay, even though no one is connected to the device. Does it do this to run some network testing or could it be some failure or intrusion? I remember that previously the router made several connections with Avira because of the security service, which decreased after an update. I performed the blocking of these sites, but then the other devices can not access either. If anyone wants to help me with this I'm very happy, thank you
