When I finished the deployment, I find that I can not access the Horizon UI through public IP. The response is something like "service unavailable"
Public IP is accessible through ping. I find that the service ports are on the list through cli:
Horizon is accessed normally when using the the host's IP address(where the public IP is located). When I switch over the public IP to the another Controller node, the Horizon works correctly. After the switchover, nearly all the "health check" are passed.
I have happened to this issue several times with different ISO/version.
