Key Observations

1. Version 1.4.6: Shows DNS queries being processed successfully with replies
2. Version 1.4.8: Shows mDNS discovery working but lacks the actual DNS query/reply traffic seen in 1.4.6
3. Both versions discover devices via mDNS successfully
4. Version 1.4.8 appears to start normally but may not be processing DNS queries properly

Additional Notes

• IPv6 availability: false (both versions)
• Network interface: eth0
• Container IP: 192.168.69.169
• DNS server listening on: 127.0.0.1:53
• Bootstrap DNS: Personal ControlD IP

Hmm, could you please ensure that your reuqests are routed correctly to the container?

I have tested and requests are still be served normally:
