Comment (by lichttraeumer):

 Some more information about the 302 redirect after logging in:

 update-core.php / themes.php / nav-menus.php / wp-admin.php /customize.php
 triggers an 302 to https://<my-domain.de>/wp-
 admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2Fupdate-core.php

 The response code for the redirected target url is 404 every time.
 Deactivating all plugins does not help!
