I think, that there is no issue,

because next link works fine:
http://192.168.56.10:9990/console/App.html#home

and with this link
http://192.168.56.10:8080/auth
I getting answer: 404 - Not Found

and in both domain.xml and host.xml are interface definitions this way:
    <interfaces>
        <interface name="management">
            <any-address/>
        </interface>
        <interface name="public">
            <any-address/>
        </interface>
        <interface name="unsecure">
            <any-address/>
        </interface>
    </interfaces>

By default Wildfly only binds to localhost (127.0.0.1), and is not reachable via any external network interfaces.

Running in domain mode is an advanced Wildfly topic, so I suggest you check Wildfly documentation:
 
https://docs.jboss.org/author/display/WFLY9/Interfaces+and+ports
https://docs.jboss.org/author/display/WFLY9/Domain+Setup


A quick way to bind to all the network interfaces in standalone mode is to use -b 0.0.0.0 as a parameter to standalone.sh. But that doesn't work for domain mode AFAIK.
