I am using Wildfly server for my application. I am running this server through intellij plugin. Whenever I run this application I am getting an error message
"Error running 'JBoss 9.0.1.Final': Unable to connect to the localhost:8080"
Here is my configuration in intellij.
Edit your standalone.xml, add this to it and try again.
Also, check your Java version. Wildfly 9 uses Java 7/8, maybe you need to downgrade Java version or update Wildfly to 14 or 15.
<interfaces>
<interface name="management">
<inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
</interface>
<!-- add the code below -->
<interface name="public">
<any-address/>
</interface>
<interface name="any">
<any-address/>
</interface>
</interfaces>
You can check here the best versions of each, so you can start your server without problems. Regards.
