I'm attemptinng to POST a data file to an Apache HTTPS server running locally on my PC, but it fails with QNetworkReply::UnknownNetworkError every time....
No activity is logged in the Apache server log files.
Even if I'm using the wrong certificate file, shouldn't I expect to see something in the Apached log files?

I'm using the QNetworkAccessManager:: post() method, and have hooked on to the SIGNALS: finished, authenticationRequired, proxyAuthenticationRequired, sslErrors, networkAccessibleChanged.
Only the finished slot is invoked, with the QNetworkReply object containing error 99...

Where should I start looking for the error of my ways?
HEEELLP! Any hints and tips will be greatly appreciated )

The Apache server is Apache 2.2.21 with mod_ssl/2.2.21, OpenSSL 0.9.8r.
