Since the TLS change was implemented, the Standalone suite attempts to reach authelia-frontend:3001. This only works for the dist/CI based workflow as nginx is run in place of node and the respective ports are exposed.
This change will attempt authelia-frontend:3001 initially for the Standalone suite but given the server is unreachable in the dev workflow, it will mark authelia-frontend:3001 as unavailable for 180s and route all requests to authelia-frontend:3000 instead.
