1. Check whether your internet connection is alive with well known host. For example you can use the following request:

NSMutableURLRequest req = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.google.com"]]; NSHTTPURLResponse urlResponse = nil; NSError *error = [[[NSError alloc] init] autorelease];
NSData *data = [NSURLConnection sendSynchronousRequest:req returningResponse:&urlResponse error:&error];
[req release];

1. Then do the same for your url.
