CUG login not working on publish server after restart
We have configured CUG for certain pages in our site and configured a login page to which all the unauthenticated requests should be redirected to. After restarting our AEM 6.3 SP2 publish server, the login for CUG protected sites is no longer working.When we hit the secure page, the publish server returns a 404.Any ideas what could be the problem?
