Troubleshooting blocking with PFBlockerNG - Best Practices Welcome

I find myself troubleshooting PFblocker issues and wanted to pick everyone's brain on best practices.

I use DNSBL blocking, GeoIP blocking, and DNS over HTTPS/TLS/QUIC Blocking.

When something is blocked and not working, my standard procedure is to go PFBlocker Unified reports page and look for what is being blocked, add the domain to my whitelist and try again. While this has worked in the past, there are many times where I no longer show anything being blocked in the unified log and still I am having issues.

How do you fix issues when you can't see any clear logs being blocked with PFBlocker?

I know this specific issue is a PFblocker issue because when I bypass, it works fine.

Thanks for your tips!
