Update your browser to the current SSL protocol support

Users can switch to a different browser which can serve as the test here. Also, SSL handshake works, while the browser using isn't updated correctly. There is a protocol mismatch. This needs to be corrected on the browser. When the user opens the proxy settings, you can click Advanced. You have to make sure TLS 1.2 is checked and also make sure that the boxes for SSL2.0 and SSL 3.0 are unchecked. 

Make sure your server supports SNI

The server name indication allows a server to host multiple TLS certificates on the same IP address. The SNI isn't enabled, and multiple TLS certificates are hosted on the server. The user will get a handshake failure because the server isn't told which certificate will be connected. 

Your error may be due to a cipher suite mismatch.

Cipher suites are algorithms that will secure SSL/TLS network connections. The server uses cipher suites which Cloudflare doesn't support, this will cause a handshake error. The user can use the same Server Test Tool from above to check on cipher suite mismatch.
