Issue with running the docker container

[gvsrini]

I instantiated the docker container as follows:
docker run --add-host keycloak:192.168.29.160 -p 8085:8085 -p 8084:8084 6a3

It's giving this error. Can you guide me how to go about it.

This application has no explicit mapping for /error, so you are seeing this as a fallback.
