Troubleshooting DNS resolution issues involves checking several things. First, verify your OpenWrt configuration is correctly pointing to Cloudflare's IPv6 DNS servers. Next, check your router's logs for any DNS-related errors. Use online DNS lookup tools to see if you can resolve domain names. Also, check your network configuration to ensure that your devices are configured to use IPv6 and that they can reach the router. Finally, ensure that DoH/DoT is enabled and functioning correctly. Possible issues could include misconfiguration, DNS server unavailability, or network connectivity problems.
