QtWebEngine

Loading should work this way, if you use the correct file format QSslSocket::addDefaultCaCertificates(certdata.pem) Look here: https://curl.haxx.se/docs/caextract.html You also need SSL error handling - use this as a working base: connect(webGUI->page()->networkAccessManager(), SIGNAL(sslErrors(QNetworkReply*, const QList<QSslError> & )), this, SLOT(HandleGUIsslErrors(QNetworkReply*, const QList<QSslError> & ))); void QTGUI_MainWindow::HandleGUIsslErrors(QNetworkReply* reply, const QList<QSslError> &errors) { foreach (QSslError e, errors) { qDebug() << "GUI SSL error:" << e; QByteArray qbTemp; qbTemp.append(e.errorString()); } //reply->ignoreSslErrors(); // this is only a hack !! reply->abort(); } HTH

@Aleksej-Ivanovic I installed the MSVC community edition and things are working now. Thank you.

If you are still seeing ERR_SSL_PROTOCOL_ERROR perhaps read here ... https://bugreports.qt.io/browse/QTBUG-52068

Thanks. I had the same issue but I did not have enough time to investigate. So I will try to update graphics driver as you did.

@SGaist @agarny Looks like this is fixed with QT 5.6 for OSX. I used the brew version. Thank you for your help.

I opened a bug report QTBUG-51971

Apparently, everything works in Qt 5.6.0...

This is problem is ok ! Find the "qmake_extras.gypi" (in qt-everywhere-opensource-src-5.4.0/qtwebengine/src/core/): { 'make_global_settings': [ ['CC.host', '/usr/bin/gcc'], ['CXX.host', '/usr/bin/g++'], ['LD.host', '/usr/bin/g++'], ['CC', '/opt/codesourcery/bin/arm-none-linux-gnueabi-gcc'], ['CXX', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++'], ['LD', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++ -lz -ldl -lpng -lglib-2.0 -lgthread-2.0 -ljpeg -lsqlite3 -lxml2'], ], 'target_defaults': { 'target_conditions': [ ['_toolset=="target"', { 'include_dirs': [ '/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include', '/usr/local/tslib/tslib1.0/include', '/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/include', '/usr/include', '/home/ubqt/usr/local/include', '/home/ubqt/icu/source//common', '/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.8.3/include/', ], 'cflags': [ '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include/dbus-1.0', '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/lib/dbus-1.0/include', ], }], ], }, } ['CC', '/opt/codesourcery/bin/arm-none-linux-gnueabi-gcc'], ['CXX', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++'], ['LD', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++ -lz -ldl -lpng -lglib-2.0 -lgthread-2.0 -ljpeg -lsqlite3 -lxml2'], ], 'target_defaults': { 'target_conditions': [ ['_toolset=="target"', { 'include_dirs': [ '/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include', '/usr/local/tslib/tslib1.0/include', '/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/include', '/usr/include', '/home/ubqt/icu/source//common', '/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.8.3/include/', '/home/ubqt/libcap/include', ], 'cflags': [ '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include/dbus-1.0', '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/lib/dbus-1.0/include', ], }], ], }, } The context is repetition. Just delete the repetition context. Before delete it, please check the "include_dirs". Sometimes I modify include path in my qmake.conf. When make qtwebengine, the "qmake_extras.gypi" will load qmake.conf again. So, please check different the "include_dirs". If there are different, modify it, Just like: { 'make_global_settings': [ ['CC.host', '/usr/bin/gcc'], ['CXX.host', '/usr/bin/g++'], ['LD.host', '/usr/bin/g++'], ['CC', '/opt/codesourcery/bin/arm-none-linux-gnueabi-gcc'], ['CXX', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++'], ['LD', '/opt/codesourcery/bin/arm-none-linux-gnueabi-g++ -lz -ldl -lpng -lglib-2.0 -lgthread-2.0 -ljpeg -lsqlite3 -lxml2'], ], 'target_defaults': { 'target_conditions': [ ['_toolset=="target"', { 'include_dirs': [ '/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include', '/usr/local/tslib/tslib1.0/include', '/opt/codesourcery/arm-none-linux-gnueabi/libc/usr/include', '/usr/include', '/home/ubqt/usr/local/include', '/home/ubqt/icu/source//common', '/opt/codesourcery/lib/gcc/arm-none-linux-gnueabi/4.8.3/include/', '/home/ubqt/libcap/include', ], 'cflags': [ '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/include/dbus-1.0', '-I/home/ubqt/FSL_LTIB_3.0.35/L3.0.35_4.1.0_130816_source/source/ltib/rootfs/usr/lib/dbus-1.0/include', ], }], ], }, } Save "qmake_extras.gypi", continue make.

Yes I figured it out... The problem is a lot of new documentation (esp. 5.6) doesn't provide even the most simple usage examples even for such a simple thing as changing the user-agent. Marking as solved.

Am suffering from the same issue.. still havent checked if it changed in 5.6

@SGaist Thank you!

I found that I was missing several files that, if not present, will cause the app to crash when QWebEngine is used: qtwebengine_resources.pak qtwebengine_resources_100p qtwebengine_resources_200p.pak.pak QtWebEngineProcess.exe icudtl.dat If I use the windeployqt.exe tool, it properly places these files with my exe.
