Problem with ccTLDs sources in Whois add on

Hello.
I want to get whois info about .pl domains.
Whois add on by default use whois.iana.org website for that. But this website gives not valid output. Lets check example url - http://wp.pl.

Outpus is as follows:

Quote:refer: whois.dns.pl

domain: PL

organisation: Research and Academic Computer Network (...)

That means it gives me info about main organisation, which register domains in Poland - NASK (DNS.pl), but not about a particular domain.
The same problems with other ccTLD, like .de - refer: whois.denic.de

I've tried to train Scrapebox with other sources, but I was not successfull.
Polish main domain registry - http://www.dns.pl/cgi-bin/whois.pl requires captcha (I don't use decaptcha service as it too expensive).
I've tried to use other services, like who.is, but always I'm getting errors
Edit: now I don't use HTTP proxies and right now there are no errors.

Now I have problem with training Scrapebox. It gives me no data for Who.is
I understand that I can use any ASCII characters? Like Tab (9) or enter (10)?
Then for who.is I do the following training - Registered before - "created:"; Registered after - "#10". What's wrong with my training? As I results I have no data. The same with "whois.net" and "whois.com".



Could you help me with finding good resource for checking PL domains?
