Unfortunately Doc Flabby is correct and sscentral.sscuservers.net doesn't support the unencrypted communication. Hopefully I can port the (subspace) encryption from my Java client to the PHP script. If someone can help me or give me some tips, please do PS. Doc Flabby, if you read this, your directory server isn't working anymore. It's online but it stops sending the zone list after it has send 22% of it.
