There is 1 solution and 2 workarounds for this issue:
Upgrade to Applications Manager 9.3 which requires a custom SSL certificate for connection authentication. This custom keystore is required to be generated and copied to master, remote agent, and client machines.
Applications Manager's documentation does cover the topic for keystore file names/locations and optional password encryption which can be found at the below link:
For information on creating keystore, please refer to your OS Admin or Oracle as this is process is an external process using Oracle's java keytool.
Downgrade Java version to a pre-Java 8 update 201 version
Update Java's java.security file and remove the anon (anonymous) and NULL ciphers from parameter "jdk.tls.disabledAlgorithms". Below is an example of what the parameter looks like.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \
EC keySize < 224, 3DES_EDE_CBC, anon, NULL
