QtWebKit to QtWebEngine migration problem
I have a "problem" with this on one of my computers, I load a .html file to run google maps, inside the html file there is this code: <script src="https://maps.googleapis.com/maps/api/js?v=3.exp"></script>
on my main computer everything work OK but on the other I need to change to: <script src="http://maps.googleapis.com/maps/api/js?v=3.exp"></script> .
with QtWebKit https work on both computers.
Qt Creator 3.6.0

Wireshark get this when using "QtWebEngine":

Any idea why application use TLSv1.1 instead of TLSv1.2 ? this does happen om some "Client Hello" calls not all...
I assume this is either missing/bad documentation or a bug, I don´t know enough to debug this "problem" further.
I have made "some" progress...
1: Made a clonezilla image of non-working computer.
2: I installed a clonezilla image from the working computer, --not working.
3: Installed Fedora 23 + Qt5.6.0 from scratch, --not working.
4: Reinstalled old clonezilla non-working image.
5: I Uninstalled QT ,removed all QT folders & configfiles I found in home directory rebooted ,-- now my application WORK as expected with the Arch Linux installed qt5* files.
6: I can install everything exept "Desktop gcc 64-bit" from the online installer......
This is an ugly workaround for now.
If you are still seeing ERR_SSL_PROTOCOL_ERROR
