Elasticsearch OrclAuthPluginRestFilter error

I am trying to install Elasticsearch 6.1.2 into a DEV environment, for Peopletools 8.56.15 environment.  I installed ES with a silent install, and I started the process, and I have verified the 9200 port is listening.

I am following (Doc ID 2281565.1) to integrate Peoplesoft with Elasticsearch.  When I go into Peoplesoft and ping the elasticsearch, I get this error.  I double checked my password for esadmin and people in the silentinstall.config.  We are not using SSL on the PSIGW.

Any thoughts on the root cause of this error?

{"error":{"root_cause":[{"type":"orcl_auth_plugin_exception","reason":"Exception while authentication "}],"type":"orcl_auth_plugin_exception","reason":"Exception while authentication ","caused_by":{"type":"exception","reason":"Failed to decode ciphertext, decryption error. Last unit does not have enough valid bits"}},"status":401}
