— Solution:
— 1579149.1

— Edit $DOMAIN_HOME/config/config.xml and add the following line:

<listen-port>5557</listen-port>

to the node manager section.  Here 5557 is the modified port. You need to change to the port number of yours if it’s different. The updated section looks like this:

<node-manager>
<name>localmachine</name>
<listen-address>localhost</listen-address>
<listen-port>5557</listen-port>
<password-encrypted>{AES}vs3A2XWw1xx22YbzEbmv8pl0QPGawNC4gBzhBgZwhnY=</password-encrypted>
</node-manager>
