If the application server and edge device fail to share a mutually supported cipher suite, it will cause errors. Many times, it happens within a network, if youвЂ™re doing SSL bridging, where an edge device receives and decrypts HTTPS traffic and then re-encrypts it to send it to the application server. No doubt, itвЂ™s less likely that you get a site that only supports a single cipher suite. Earlier, Cipher Suite has algorithms that handled:Дifferent Organizations and Government Agencies have different types of encryption standards that suggest different kinds of cipher suites so clients can have different options while being able to find a mutually acceptable cipher. Nevertheless, Cipher Suites used by TLS 1.3 has been refined. SSL/TLS isnвЂ™t just a single algorithm that handles everything on its own but a combination of numerous algorithms that serves different functions and work with each other to make up SSL/TLS. Presently all we can suggest is that TLS 1.2 or TLS 1.3 must be used, or else support must be added for it.ДЄ cipher suite is quite similar to the Protocol Mismatch.

In this above example, the client must be recommended to upgrade their browser, or else it must be latest with the latest TLS version supported. Nevertheless, the server shouldnвЂ™t fix this as well. So, itвЂ™s likely that the server wonвЂ™t support backward versions. The client supports TLS 1.0 and TLS 1.1, whereas the server supports TLS 1.2.ДЄs shown in this example, the TLS protocol is not supported mutually.So, if the SSL/TLS Handshake Failure error is due to protocol mismatch, it generally means the client and server do not have mutual support for the same TLS version. And, sites were also advised for adding support for TLS 1.3 at their earliest.

Earlier back in March 2018, the final version of TLS 1.3 was published as RFC 8446 by the IETF.

TLS 1.2 came more than a decade ago, and small segments of websites still fail to support it. And when itвЂ™s about ciphers and protocols, itвЂ™s advised to move forward rather than backward. ItвЂ™s one of the errors which can happen due to both the server-side or the client-side, and generally, itвЂ™s not worth solving depending upon the circumstance.
