I recently enabled the Blocklist features under Services > Unbound DNS > Blocklist to block ads on network level and use all of the DNSBL list except the Blocklist.site.

After I enabled this feature, Netflix will give me tvq-pb-101 error code. I disabled it and it works fine again. How do I know which domain in the list is blocking Netflix?
Unless you are using Linux or Mac I would recommend removing windows spyblocker blocklists (they literally block everything microsoft related, even updates, e-mail, xbox app and windows store)
Also one of the blocklists could be blocking netflix, so de-select blocklists one by one and restart unbound each try untill it works.
from advanced settings, there is option to use custom blocklists, so I would recommend using some of those instead
