nostale auth outdated? did cert change?

Hi
I've been trying to use morsisko's NosTale Auth lib and something is not working for me right now. Few months ago it worked as expected but right now seems like something changed.

here is the error:
[Only registered and activated users can see links. Click Here To Register...]

seems like something wrong with cert.
Is there new cert inside GFs client? Tbh I have no idea how can I check it out (and dump cert from client or something)

I would be thankful for help.

greetings

Hey, as far as I know, yes the certificate has been changed + there is another required field called black-box that has to be passed. Didn't see anyone fixing/implementing those changes. Anyways good luck with that if you continue with that.

EDIT: Looks like someone has been able to create POC [Only registered and activated users can see links. Click Here To Register...]
