Domains show as blocked in Top Blocked Domains but blocking disabled #810

I'm trying out technitium, great piece of software so far!

However, I'm having a strange issue with blocking. I have blocking disabled under Settings, Blocking, Enable Blocking unchecked. There are also nothing under Allow/Block List URLs or anything else set on that page, except Allow TXT Blocking Report checked.

I'm still seeing eight domains on the dashboard, Top Blocked Domains widget. Does it mean they are blocked or can they end up on the list for any other reason. If they are blocked, how can I find the reason for that and unblock them. Or is it a bug?

Thanks for the post. Do you have any forwarder configured? If yes then its the forwarder that is blocking the domain name. The DNS Server is capable to detect if the upstream/forwarder is blocking the domain and records that in the stats which is probably why you are seeing that on the dashboard.

I also noticed this. @ShreyasZare Is the trigger condition for this detection the upstream server returning 0.0.0.0?

Yes, that is one type of condition. It also checks for the Extended DNS Error codes in response if the upstream server supports it.
