QSslSocket error when SSL is NOT used

Question

I have noticed this output in two of my Qt applications that use QNetworkRequest to load some data from outside over QNeworkRequest :

QSslSocket: cannot resolve TLSv1_1_client_method
QSslSocket: cannot resolve TLSv1_2_client_method
QSslSocket: cannot resolve TLSv1_1_server_method
QSslSocket: cannot resolve TLSv1_2_server_method
QSslSocket: cannot resolve SSL_select_next_proto
QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb
QSslSocket: cannot resolve SSL_get0_next_proto_negotiated

One example of the request which causes these warnings to appear is

QNetworkReply reply = m_nam->get(QNetworkRequest(QUrl("http://api.openweathermap.org/data/2.5/forecast?id=2835297&mode=xml")));

I am reasonably sure that there is no TLS/SSL involved in any of the queries, all are plain HTTP. The messages appear always after the first request is dispatched, regardless of URL. I have no intention to ude SSL at all, there is no mention of SSL in the code, which means I can't ignore the warnings programatically.

My setup is Windows 7 64 bit, MSVC2013 and MinGW, Qt 5.3.2. The messages appear regardless of the compiler used. No OpenSSL or other SSL development libraries are installed.

And the question is: How do I get rid of these warnings?

Answer 1

Can be disabled related warning messages with QLoggingCategory::setFilterRules("qt.network.ssl.w arning=false");
