+# This is an advanced feature used to control the public server endpoint returned to clients during Well-known discovery.
+# You should only use this if you want mobile apps to access the immich API over a custom URL. Do not include trailing slash.
+# NOTE: At this time, the web app will not be affected by this setting and will continue to use the relative path: /api
