[SOLVED] Weird messages from webpages

I am seeing some weird messages since few days, like opening
http://static.myopera.com/community/css/forum.css
shows

Destination could not be reached. (com.nokia.warlock.protocolstack.exceptions.UnresolvedHostException: /community/css/forum.css)
      
It is clear that the message is not from Opera’s site, because same message comes from other sites which has nothing to do with Opera.
Any help?
Answer #1
Your issue might be DNS related. Use OpenDNS or Google DNS.
The site you linked us to, is just a stylesheet, not a site =(
Answer #2
I know that’s CSS, this happens rarely with some sites also. Like it just happened to http://forums.cnet.com/7723-6122_102-506780.html and http://forum.kaspersky.com/index.php?showtopic=64117. It is just random. It doesn’t seem DNS issue, because the IP resolved is correct for the site. I tried sniffing packets, these sites send 502 Gateway errors with this message.
Answer #3
Well, if the DNS has been properly resolved to an IP, then its either your ISP or your browser.
Clear your settings, cache, and cookies and try again.
If you think its your ISP, use a proxy or a vpn.

Isn’t a 502 Gateway error a denial of access?
It is on my college’s proxy.
e.g. If you have no internet credit left, trying to access any webpage will produce a “502 Gateway error” response.

It could be possibly my ISP. It shows Nokia in name, might be my modem so, because the modem is Nokia USB Modem.

No, that’s not the case.
I am surfing lot of pages now to get error again, but it hasn’t happened since last half hour.
EDIT: Error again appeared on http://www.youtube.com/watch?v=RtJIbg_hWmI
EDIT: OMG! I opened http://pgl.yoyo.org/http/browser-headers.php and I saw lot of new headers that my browser is not sending:
X-Forwarded-For:    ***myip***
X-Nokia-Remotesocket:    ***myip***:1727
X-Nokia-Localsocket:    ***newip***:80
Accept:    */*
X-Nsn-Gateway-Id:    NBG/4.0/0
X-Nsn-Bearer:    GPRS
X-Nsn-Maxdownlinkbitrate:    512
X-Nsn-Maxuplinkbitrate:    512
Proxy-Connection:    close
EDIT: OK Solved. My phone was using another ISP’s settings. I forgot to change it, my ISP should forcelly reject the connection, but it didn’t happen. Now I changed settings and everything works fine and new headers are gone.
