If you get WASX7070E error when you use wsadmin command, it means the script takes one of the argument as SOAP_CONNECTOR_ADDRESS.

Once make sure to the SOAP_CONNECTOR_ADDRESS port (dmgr port in ND environment), now take look at  the \AppServer\profiles\AppSrv01\properties\wsadmin.properties and look for value for com.ibm.ws.scripting.port . Both port should be same.

taken error in my environment:

WASX7015E: Exception running command: “AdminConfig.list (‘Server’)”; exception information:
com.ibm.ws.scripting.ScriptingException: WASX7070E: The configuration service is not available.
