 : Security Error occurred on connection to: tcp://127.0.0.1:63838, User name [1rTDfFb2MR41jiVtN3xgpJys] or password is invalid.

Looks like your job agent is trying to connect with bad information.  This can happen if the server was upgraded but agents were not.  

You need to ensure that the information inside of execution.properties matches what your job agent config.properties has.

---

Inside of the config for a job agent at job-agent\home\config\agent.properties you will find something like the following

"##

1. Queue related configuration in case ActiveMQ is enabled as the broker.
   #
   jobagent.queue.activemq.host = 127.0.0.1
   jobagent.queue.activemq.port = 5672
   jobagent.queue.activemq.username = 
   jobagent.queue.activemq.password =

This should match what is in the execution.properties file from the rapidminer server home at \rapidminer-server\rapidminer-server-home\configuration\execution.properties

#

1. ActiveMQ configuration / Queue configuration
   #
   jobservice.queue.activemq.embeddedBroker.enabled = true
   jobservice.queue.activemq.uri = failover:(tcp://0.0.0.0:5672)
   jobservice.queue.activemq.username = 
   jobservice.queue.activemq.password =

The agent should be restarted once you match the information
