errno: -111 ECONNREFUSED starting up discord bridge

Server is set up using the matrix-docker-ansible-deploy project. The appservice-discord is enabled through this as well. The bot is setup and configured on the Discord side and has successfully been joined to the Discord server. When trying to start up the appservice-discord service on the Matrix server side I get the following:

This is an otherwise functioning Matrix server so I'm not quite sure what's going on.
