Scripts with update check are not working anymore.

[Outbreaker]

Hi

I have a strange problem i noticed yesterday that every script that checks for updates are not working anymore even ispCP won't work and gives my this error message:
"Couldn't check for updates! Website not reachable."
I also tested an RSS Script that displays RSS feeds to HTML and this worked without any problem and i have also checked if "allow_url_fopen" is set to "On".
I don't know what this problem could be i changed nothing only auto update is enabled on my VPS. Hop someone here knows how to fix this strang problem im little bit lost.

Ok i found out what the problem was it was because i added my IPv6 IP to my Domain.
Is this a ispCP bug or did i do something wrong?
