Deployment fails with errors regarding application code
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.
SSL not working in legacy browsers
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.
Some applications on my Layer deploys, some of them not
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.
