I started the AEM author instance by the start.bat ( crx-quickstart > bin > start.bat ), there the server is showing the startup complete but when i am hitting on link localhost:4502 it is showing connection refused ??
Thanks @Jorg i searched the port number string in log it showed the result, and the loopback link "http://127.0.0.1:4502/" also was not working, but thanks for the help
