nslookup from lan clients - stucks

[YBS-PC]

I use adguardhome on my router as a dns server on my local network. I specified port 54 in dnsmasq, and left 53 for AGH. And recently I started noticing delays in DNS requests and these delays are only over the local cable network when using the nslookup command, several requests come from responses about exceeding the time. I have tried different firmware versions, tried to restore the old settings, but nothing helps. Adguard home settings were also reset and did not help either. But if you turn off adguard home and give port 53 dnsmasq and specify the higher dns 1.1.1.2, then everything works fine. My network is such that the provider's cable is connected to the glinet mt2500 with openwrt-immortal firmware, its lan port is connected to the asus router (media bridge), asus distributes the network further both via wifi and cable. I tried connecting the computer directly to the mt2500 router, it didn't help either - there are the same delays. Can someone help and suggest what this might be related to?
