Checking any of our domains with SSLLabs.com (SSL Server Test (Powered by Qualys SSL Labs)), we get the following error for IE11 on Windows 8.1: Server sent fatal alert: handshake_failure

Is this due to SSL ciphers? If yes, what ciphers could we be using that are still safe?
Currently using this: ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384
