Description kiyoMatsui 2020-05-17 14:36:34 UTC

SUMMARY
That "SSL Certificate error!" but it seems to happen when loading a non existent page (404) of a popular website. existing urls of the same website would otherwise accept the handshake. 

STEPS TO REPRODUCE
1. In falkon search for https://www.theguardian.com/exampleBadURL
2. 
3. 

OBSERVED RESULT
output:
[11445:11460:0517/145756.472087:ERROR:ssl_client_socket_impl.cc(941)] handshake failed; returned -1, SSL error code 1, net_error -200

Then:
"SSL Certificate error!" dialog.

EXPECTED RESULT
No handshake failed prompt (for the right reasons of course!)


SOFTWARE/OS VERSIONS

Linux/KDE Plasma: KDE neon 5.18
(available in About System)
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.69.0
Qt Version:  5.14.2

ADDITIONAL INFORMATION
Currently can only repro with this site. Doesn't happen with say reddit or with google but does happen with The Guardian (Guardian is a major newspaper in the UK). It also doesn't occur if an instance of the page is open on another Tab. Something is off!

Having looked at the issue this is out of the scope of falkon and more of a QtWebEngine issue. You will also get the same behavior using the simple browser sample.
