Troubleshooting

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

Check the node['applications'] parameter in 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.
