I imported User Attributes from another environment. Things looked fine. After that added one more User attributes and the screen seems to have frozen. I tried logging into the environment from another browser not the UI won't come up.
I checked ACM status, it is running. I thought of restarting acm but I am getting following error message.
org.jboss.as.cli.CliInitializationException: Failed to connect to the controller
