SP13: Security Token Service is not available

As may be reported by the Health Analyzer or as a message in the System Event Application Log:

The SharePoint Health Analyzer detected a condition requiring your attention.  The Security Token Service is not available.
The Security Token Service is not issuing tokens. The service could be malfunctioning or in a bad state.
Administrator should try to restart the Security Token Service on the boxes where it is not issuing tokens. If problem persists, further troubleshooting may be available in the KB article. For more information about this rule, see "http://go.microsoft.com/fwlink/?LinkID=160531".

This indicates that the SharePoint Web Services Root application pool is stopped. Open Internet Information Services (IIS) Manager, expand server then click on Application Pools – right click on the SharePoint Web Services Root and select Start:



Other possible causes:
The Security Token Service hasn’t been provisioned
1.       Login to a SharePoint server as the Farm Account
2.       Open the SharePoint 2013 Management shell using Run as administrator
3.       Enter in the following commands:
$sts = Get-SPServiceApplication | ?{$_ -match "Security"}
$sts.Status
$sts.Provision()

Incorrect Authentication Settings in IIS
1.       Open Internet Information Services (IIS) Manager
2.       Expand the Sites folder
3.       Expand the SharePoint Web Services folder
4.       Click on the SecurityTokenServiceApplication to select it
5.       In the Features pane in the IIS section, double click on Authentication
6.       Right click on Forms Authentication and select Disable (for SharePoint,only Windows and Anonymous access should be enabled for tokens and the claims service to work correctly)

Bad data in the Web.config File
Check the web.config file in the site for errors (use Windiff to compare to a working web.config) and/or remove any manual changes that may have been made.
