Issue:1

When you see below type of issue:

[jbossuser@redhat bin]$ ./jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /] connect
The controller is not available at localhost:9990: java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: Connection refused

Solution:

Step 01:

Comment (or you can remove) following line from /bin/jboss-cli.xml

default-protocol use-legacy-override="true">remote+https</default-protocol

Correct protocol Ex:

<default-protocol use-legacy-override="true">remote+http</default-protocol>

<!-- The default controller to connect to when 'connect' command is executed w/o arguments -->

<default-controller>

    <protocol>remote+http</protocol>

    <host>localhost</host>

    <port>9990</port>

</default-controller>

Step 02:

In my case i have alredy created a Administrative user hence, I have statup the CLI with following commnad

./jboss-cli.sh --user="<user>" --password="<password>" --controller=remote+http:<your IP>:<port> --connect

Example :

./jboss-cli.sh --user="Admin" --password="Password" --controller=remote+http://19.199.115.172:9990 --connect

Make sure your wildfly is up and running. If you have used different port for the admin console it should be added .
