Issue/Introduction

     An APM 10.5.x Docker Agent has been configured to connect to the Enterprise Manager's REST API using HTTPS by specifying the following in the docker.properties file:

apm.accesstoken=<token>
apm.atc.resthttps=https://<host>:<port>/apm/appmap/graph/vertex/

Despite this configuration, the Docker Agent attempts to establish an HTTP connection. The following error is logged:

[ERROR] [com.ca.apm.microservices.docker.DecorateAgentNodes] com.wily.isengard.messageprimitives.ConnectionException: HttpHostConnectException: Connect to <host>:80 [Host/<IP Address>] failed: Connection refused: connect
