NSURLConnection Lost Connection

I have an app with 100k+ users that connects using a SOAP web service. Everything works fine for most users except sometimes using NSURLConnection I keep getting the error: 

Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo=0xac16c70 {NSErrorFailingURLStringKey=https://mail.scripps.org:443/ews/Exchange.asmx, NSErrorFailingURLKey=https://mail.scripps.org:443/ews/Exchange.asmx, NSLocalizedDescription=The network connection was lost., NSUnderlyingError=0x133b0eb0 "The network connection was lost."}

This only happens for certain servers. The servers have NTLM authentication which works 95% of the time but for some reason I'm getting the error and I have no idea why.

Any help appreciated.

This Question also identified the problem I was having. Instead of soap, I'm using jsonrpc.

The solution was simple. I needed:

[myMutableURLRequestObject setHTTPMethod:@"POST"];

Network connection failures happen, you just need to handle them gracefully. One solution may be to retry the connection 1 or more times until it succeeds after you are sure there is a network connection. Rough example below:

if([error domain] == NSURLErrorDomain && 
    [error code] == NSURLErrorNetworkConnectionLost && 
    retryCount < kMaxRetryCount)
{
    [self retry];
    ++retryCount;
}
