Issue/Introduction

Detection server shows up as unknown and you see error "javax.net.ssl.SSLHandshakeException: no cipher suites in common" in Box Monitor logs.

Resolution

On the Detection server navigate to the config directory and open communication.properties file with a text editor.  Backup the current setting and update it with the following:

SSLcipherSuite = TLS_RSA_WITH_AES_128_CBC_SHA256

To backup the setting just comment it out with a # character at the very beginning and use the above line and paste it below it.  Restart the detection server services and verify.
