Pihole blocking whitelisted domain/none blocked domain

Please follow the below template, it will help us to help you!

Hey,

Expected Behaviour:

www.postbank.de should open without problems

Actual Behaviour:

pihole seems to block it (not shown in query log)
more information: https://discourse.pi-hole.net/t/banking-postbank-de-rai-login-is-not-working
(i 've been told to create a new topic for this)

Debug Token:

thanks a lot.

same problem for me

Can you just add it to the whiteless?

Looks like its blocked on some of my lists. Maybe just whitelists and see what happens.?

$ pihole -q postbank.de

Match found in list.42.hosts-file.net.domains :

postbank.de.kundenkonto-postbank-6756370708-postbank.ru

www.postbank.de.kundenkonto-postbank-6756370708-postbank.ru

a strange thing. the url

Kartenlimit anpassen | Postbank

is working. the url

https://www.postbank.de

not

I followed the old discussion as a lurker, but i might have a solution to this problem, which i run into myself the last couple of weeks.

To me it looks like postbank.de doesn't resolve, only if Cloudflare is one of the chosen upstream-providers. After i disabled 1.1.1.1 an swiched to Google & Level3, postbank.de has no problem loading.

On top, i found a just 18 days old support-posting from a Cloudflare Staffer, explaining that they have trouble resolving postbank.de

The root cause is that postbank.de nameservers return slightly invalid proof of non-existence, which breaks resolvers implementing RFC8198 . We’re trying to work with the operator to fix this, as the only workaround is disabling DNSSEC which unfortunately brings its own problems.

@don_misu : You might want to consider removing the "solved"-Checkmark on top of the old discussion, pointing to whitelisting the scam-domain "[...]-postbank.ru" - as this does not work, it might cause more harm than good.
