SCNetworkReachabilityCreateWithName not working for all URLs

Question

SCNetworkReachabilityCreateWithName(NULL, "www.google.com") does work fine,

SCNetworkReachabilityCreateWithName(NULL, "https://domino.ese-edu.com") or

SCNetworkReachabilityCreateWithName(NULL, "https://scanner.ese-edu.com:50443")

Always fails although both URLs hit a working and responding server.

Are there any special communication (port?) requirements for this function to work?

Answer 1

You’re not supposed to pass URLs to

SCNetworkReachabilityCreateWithName

; it takes a DNS name. So your second example should be:

SCNetworkReachabilityCreateWithName(NULL, "domino.ese-edu.com")
