This error appears when starting the wsadmin utility.
~]# /opt/IBM/WebSphere/AppServer/profiles/<profile name>/bin/wsadmin.sh
Error creating SOAP connection to host . . .
Ensure the deployment manager (DMGR) is running. This error will appear if the DMGR is not running.
If the deployment manager is running, and the error persists, get the current SOAP hostname and port. In this example, the hostname is example.com and the port is 12345.
~]# cat /opt/IBM/WebSphere/AppServer/profiles/<profile name>/config/cells/<cell name>/nodes/<node name>/serverindex.xml

<specialEndpoints xmi:id="NamedEndPoint_123456789" endPointName="SOAP_CONNECTOR_ADDRESS">
<endPoint xmi:id="EndPoint_123456789" host="example.com" port="12345"/>
</speicalEndpoints>
Update the wsadmin.properties file to have the SOAP hostname and port listed in the serverindex.xml file.
~]# vi /opt/WebSphere/AppServer/profiles/<profile>/properties/wsadmin.properties
Execute the wsadmin.sh command again, the SOAP error should no longer appear, and you should be prompted for a username and password.
