Connection refused when running on device(while calling JSON service)

Hi all,Am calling a json service on a local weblogic server. When i runned on my device with the command: “ionic cordova run android --livereload” am getting the following error:

GET http://localhost:8081/ net::ERR_CONNECTION_REFUSED
Am using ionic 3
OS:win 10

ionic cordova run android --device -l

Same issue…Not working…

even after enabling cors and changes the[ this.get(“http://lap-ip:8081/”] function with lap ip instead of local host, still facing the same issues
