You have attempted to use an application which is in violation of your internet usage policy.
but when i am using https://www.google.com, then it is showing
"The proxy server isn’t responding
•Check your proxy settings
Go to Tools > Internet Options > Connections. If you are on a LAN, click “LAN settings”.
•Make sure your firewall settings aren’t blocking your web access.
•Ask your system administrator for help.
but in both the cases when i am using mozilla its working fine no issues. rest all other browsers are not working.
i used few tips on net to resolve but didnt worked for me, like
using netsh int ip reset resewtlog.txt, netsh winsock reset catalog, netsh int ip reset reset.log hit....in cmd . but nothing happened.
please suggest some other thing
