Failed to connect to the CLI: "XNIO000816"

Solution Verified - Updated -

Environment

Red Hat JBoss Enterprise Application Platform (EAP) 7.1

Issue

  • After upgrade from JBoss EAP 7.1.0 to JBoss EAP 7.1.5 the connection failed to the CLI.
  • Not able to connect to the CLI due to XNIO000816 error.

Resolution

Check if the http-interface is configured with http-upgrade enable=true, as shown below:

 <http-interface security-realm="ManagementRealm">
          <http-upgrade enabled="true"/>
          <socket-binding http="management-http"/>
</http-interface>

Root Cause

Without the http-upgrade enabled=true the http interface don't allow connections to the remote interface, like CLI.
