Internal DNS server - continuous errors - REFUSED unexpected RCODE resolving 'testnet-history.minepi.com/ANY/IN' #326

Hello - I'm running a BIND DNS server (v 9.18) on my internal network, and have the Pi Node container (v0.4.5) running on a docker desktop (v 4.22.0) container on a Windows 10 Pro machine. The container seems to be running well (block chain is fully synced, I have incoming and outgoing connections) but my DNS server's syslog is getting spammed every few minutes with the following errors:

This is the only instance of getting an RCODE refusal for my 100+ other devices using this DNS server. My troubleshooting screenshot from the Pi Node container is attached below. Any idea of what's going on here? Screenshot 2023-08-15 at 12 37 45 PM
