If you have enabled app['framework']['envs_in_console'] parameter, always disable it first and check if error occurs
again. This parameter is a "hack" on rails config/application.rb file, which inserts all application environment variables
before initializing the Rails stack. This may cause some problems (in very rare cases), and break this file.
By default webserver is configured to follow strict SSL security standards, covered in this article. However,
old browsers (like IE < 9 or Android < 2.2) wouldn't work with this configuration very well. If your application needs
a support for those browsers, set app['webserver']['ssl_for_legacy_browsers'] to true.
Check the node['applications'] parameter in :ref:`Attributes` section.
If set, it narrows down the list of applications allowed to deploy, to its value.
If not sure what to do - try to remove from your Stack/Layer config and see if this helps.
If you changed after_deploy method in your appserver, to do a clean restart, please not that ENV variables,
are not refreshed from applicatino perspective. More details are covered in Issue #142.
