qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed in windows

Why such open ssl failed errors comming

Hi RAKHISASIDHARAN!

The error you are seeing could be occurring because SSL is not available when building your Qt application. SSL is not included with Qt, so this needs to be set up separately.

Information about setting up and using SSL with a Qt application can be found on the How can I add SSL support to my Qt application? Qt wiki page.

Do you already have SSL setup? If not, does following the setup instructions on the Qt wiki page resolve the error?

Hi AndrewBladon,

I have the same issue, and after verifying that openSSL is installed on my system and the necessary .dlls are included in the debug and release directories, I am still getting the same error. 

One solution that I read elsewhere was to change the MSVC version to 2010 as it is supposedly more compatible? This seems incorrect to me and I am still searching a solution. 

The project I a working on is the most basic possible, and I have exactly followed the steps listed in the very first display_a_map tutorial on the arcGIS website. I've used the qt maintenance tool to add openSSL support, but this didn't change anything.

Any ideas as to what I might be missing?

The final solution that worked for me was to figure out which version of openSSL qt was looking for and then getting the correct version. See here for my full answer.
