QWebEngineView - handshake failed; returned -1, SSL error code 1, net_error -205

PSI_lbc

Windows 7 32bit
Based on Qt 5.13.1 (MSVC 2017, 32 bit)
Qt Creator 4.10.1
The Qt 5.13 version is using SSL lib build: "OpenSSL 1.1.1b 26 Feb 2019" and
SSL lib version: "OpenSSL 1.1.1d 10 Sep 2019"

The QWebEngineView loads a local HTML page.
The user clicks a button the page.
The button transfers from the local page to an HTTPS page.
The HTTPS page loads about 40% in release config) and to 70%(debug config) verified by loadProgress then hangs for a number of seconds seconds.
Then the handshake error occurs and is displayed.

When the Qt app is built in "release" mode there are 2 errors

[2384:1456:0219/112603.780:ERROR:ssl_client_socket_impl.cc(962)] handshake failed; returned -1, SSL error code 1, net_error -205
[2384:1456:0219/112603.780:ERROR:ssl_client_socket_impl.cc(962)] handshake failed; returned -1, SSL error code 1, net_error -205

When the Qt app is built in "debug" mode the above errors display followed by

The "-----.-----" is just to obfuscate the HTTPS URL

Thoughts?

Should I call the payment clearing company?

Is this a known Qt bug or the responsibility of the URL owner providing the payment clearing service?

Is the "handshake" issue "SSL related" or it it due to a bad certificate in the Qt QWebEngine/Chomium stuff in the 5.13 version, or a certificate on the payment clearing URL?

Is this possibly related?

libnssckbi.so is not in the 5.13 directory structure.


https://github.com/clearlinux/distribution/issues/1843

In Qt 5.13  /DevTools/Qt/5.13.2/Src/qtwebengine/src/3rdparty/chromium/crypto/nss_util.cc 

  // Load nss's built-in root certs.
  SECMODModule* InitDefaultRootCerts() {
    SECMODModule* root = LoadModule("Root Certs", "libnssckbi.so", nullptr);
    if (root)
      return root;

    // Aw, snap.  Can't find/load root cert shared library.
    // This will make it hard to talk to anybody via https.
    // TODO(mattm): Re-add the NOTREACHED here when crbug.com/310972 is fixed.
    return nullptr;

Qt version 5.14.2 has the same issue

PSI_lbc

Reverted to 5.12.2

Everything is now working again. Not sure what the issue is/was.
