Issue

The Commerce Admin panel has an infinite redirect when the backend URL is different from the default website URL.

Prerequisites:

  • Base URL is used for both backend and storefront. Base Secure URL is not used.
  • The web server is configured so that Adobe Commerce is accessible via two different URLs. URL1 is used for Adobe Commerce installation.

Steps to reproduce:

  1. Go to Admin Panel > Stores > Configuration > Web.
  2. Leave original Base URL in global configuration. It’s your URL1.
  3. Switch to Main Website scope.
  4. Change Base URL to a different URL (see preconditions to set up web server correctly). This is your URL2.
  5. Clear cache (if necessary and possible).
  6. Open Admin Panel.

Expected results:

Admin Panel is successfully opened and can be navigated. Main Website’s store is successfully opened and can be navigated.

Actual results:

Infinite redirect happens. Adobe Commerce redirects from URL1 to URL2 and continues back and forth.
