APM agent showing timeout Error (Connection Refused)

Not sure if that's what you meant by "I made sure to add in the objects and it found 16." but did you Load Kibana objects? See https://www.elastic.co/guide/en/kibana/6.6/apm-getting-started.html?

If it still does not work, could you execute this query in the Kibana Dev Tools console:

GET /apm*/_search
{
  "query": {
    "match_all": {}
  }
}
