How do I resolve an "SSL Handshake Exception" error in the EUM processor?

[#1]

Symptoms

The following error message can be found in the SSL-enabled debug logs for the EUM processor, while the processor is running and listening on port 7002:

javax.net.ssl.SSLHandshakeException: no cipher suites in common

The following error message appears on the <eum-server-host>:<eum-server-https-port>/eumaggregator/get-version page.

Diagnosis

This root cause of this issue is a wrong entry type field value in the custom keystore for the EUM processor alias.

Example:

Alias name: 'eum-processor'
Creation date: 14 Mar, 2017
Entry type: trustedCertEntry

Solution

1. Regenerate the keystore and copy into <eum installation directory>\eum-processor\bin.  
2. Make sure that the entry type value is not trustedCertEntry for the alias 'eum-processor' and it should be as "Entry type: PrivateKeyEntry".
3. Restart the EUM Server. In your computer terminal, from the EUM processor directory use the following commands:

   1. bin/eum.sh stop
      bin/eum.sh start

4. Verify the new SSL server cert works by opening the following page in a browser: https://<hostname>:7002/eumcollector/get-version
5. Confirm a successful response.
