Containerized an Open Roberta (OR) Lab server, but I can’t get the EV3 brick to find the OR server in the container. The extensive environment/configuration details are posted below. The Brick simply times out after 10-15 seconds with the screen:
Open Roberta Lab is unreachable! Reason: No access from this network! (Press any key)
For more about the OR project, please see https://www.open-roberta.org/en/welcome/
