Hello!!
I have this error in user interface, do you know what can be the cause of it?
There is an error. Please report the message (Piwik 1.12) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

I connected to the server and made
ping www.whois.com [worked OK]
ping google.com [worked OK]
wget -O - www.whois.com [time out]
wget -O - www.whois.com [form home, works ok]
telnet www.whois.com 80 [time out]
telnet www.google.com 80 [works OK]
Do you know how can I solve this?
