NSURLRequest the request time out

I've a strange problem, I'm working on a project that I've to request from a server, When requesting a URL without parameters using GET method, it works fine and return the desired data, but when using the same code to call the URL and sending a parameters to it, it fail with this error:

error: Error Domain=NSURLErrorDomain Code=-1001 UserInfo=0xed4870 "timed out"

My code is the following:

NSString *param = @"pageNumber=2";

NSURL *url = [NSURL URLWithString:@"http://myWebsite/api/Soccor/"];//When using this, it works fine
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://myWebsite/api/Soccor?%@", param]];//When using this, it gives me the request time out error.
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest addValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"GET"];
[theRequest setTimeoutInterval:10];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

Any clue why it returns error when sending parameters with the URL?

I would suggest you consider two aspects of the request:

1. You are not showing us your setting of msgLength, but I would only suggest setting a Content-Length header if you're also using setHTTPBody, in which case you'd set the Content-Length to be the length of the NSData you use as a parameter to setHTTPBody. But this is used with POST requests, not GET requests.

2. You specify application/json for the Content-Type of the request, but request does not consist of JSON. If you did that because the response is JSON, it should be noted that this header value is for your request, not for the response you expect from the server.
