The gateway is running in a Docker container, and the default server connection status of not connected indicates whether this is due to a TCP port issue or not. If not, please offer a solution.
Please see the following command for running the container.
"docker run -d -p 9088:8088 --name ignition-icpro inductiveautomation/ignition:latest -n docker-icpro -a localhost -h 9088 -s 9043"
