If this move is unsuccessful and still displays the “SSL Handshake Failed” error, the problem may not exist from the browser’s end. But, if the error vanishes and the website is connected, there may be an issue with the browser plugins or browser configurations. Try to uninstall the pl...

error conditions. The numbers especially, play a trivial role in understanding the problem/failure within theSSL/TLShandshake.SChannellogging may have to be enabled on the windows machines to get detailed SChannel messages. Please refer the following article to do so:http://support.microsoft.com/...
The TLS Handshake Protocol involves the following steps: The client sends a "Client hello" message to the server, along with the client's random value and supported cipher suites. The server responds by sending a "Server hello" message to the client, along with the server's random value. ...
When running as the server, the socket will be destroyed with an error after handshakeTimeout timeout. For TLSv1.3, renegotiation cannot be initiated, it is not supported by the protocol. M tlsSocket.setMaxSendFragment(size) Added in: v0.11.11 ...
One thing to pay attention is, if there has ever been an error on the connection, then you must close it: attempting to use the connection may put the SSL object in a bad state. Butthe error handling for the handshakelooks fine to me. ...
Error handling in the TLS Handshake protocol is very simple. When an error is detected, the detecting party sends a message to the other party. Upon transmission or receipt of a fatal alert message, both parties immediately close the connection. Servers and clients MUST forget any session-identi...
