Hi,

This is expected. Publisher by default redirects you to /content page after login but if you want you can change to any other page from using the OSGI configuration called “Day CQ Root Mapping” 

But you can access any page of publisher without login, just type url.

Access the local AEM Publish Service at http://localhost:4503 in a Web browser

Ref: experienceleague.adobe.com/docs/experience-manager-learn/cloud-service/local-development-environment-set-up/aem-runtime.html?lang=en

Are you setting the AEM as Cloud on your local?

First, there is no localhost:4503/content.html. Try login here: localhost:4503/libs/granite/core/content/login.html and go to: localhost:4503/crx/de. If you're seeing this then your server is up and running fine. If you want to go to UI then try this: http://localhost:4503/aem/start.html (this works only after you login the above url).
