Wildfly not starting due to "WFLYCTL0419: '<HOSTNAME> is an invalid value for parameter node-identifier. Values must have a maximum length of 23 bytes"

If the wildfly is not starting due to the below error, it is most likely happening because host name defined in the appserver.properties as FQDN host name is too long as it needs to be either the IP address, or PQDN or just the hostname without domain name.  

2020-10-22 15:29:28,185 ERROR [org.jboss.as.controller.management-operation] 
(ServerService Thread Pool -- 82) WFLYCTL0013: Operation ("add") failed - address: 
([("subsystem" => "transactions")]) - failure description: "WFLYCTL0419: 
'HOSTNAME-WITH-OVER-23-CHARACTERS-0' is an invalid value for parameter node-identifier. 
Values must have a maximum length of 23 bytes"

1.  Therefore, go to appserver.properties file.

2.  Make sure the wildfly host name is not defined as FQDN.

3.  Navigate to the <install_folder>/wildfly and delete the wildfly JVM that was created previously.

4.  Reconfigure Wildfly by navigating to <install_folder>/Infogix/bin and run config-wildfly script to
     recreate the WildFly instance. 

     For Windows
     config-wildfly.bat -c <myConfigName>

     For UNIX or Linux
    ./config-wildfly.sh -c <myConfigName

5.  Add the wildfly user:

    For Windows
    add-wildfly-user.bat -c <myConfigName> <WILDFLY_ADMIN_
    USER> <WILDFLY_ADMIN_PASSWORD>

    For UNIX or Linux
    ./add-wildfly-user.sh -c <myConfigName> <WILDFLY_ADMIN_
    USER> <WILDFLY_ADMIN_PASSWORD>

6.  Start Wildfly now and it should start successfully.
