## Symptoms

- * When users connect to Remote Access VPN clients, they can reach the authentication page and enter their credentials. Then, authentication fails.
* The authentication page shows "`the website can't display the page`" and the Remote Access VPN client window times out.
* This error message appears in the */opt/CPVPNPortal/logs/error_log* file:   
  "...`[php7:notice] [pid 12382] ... simplesamlphp ERR [ef17262fa4] Caused by: Exception: Unable to validate Signature`"

## Cause

One of these is the cause:  

* There is more than one Identity Provider configured for the same domain in SmartConsole.
* There are incorrect configurations in the Identity Provider object in SmartConsole. (These are usually in the **Data received from the SAML Identity Provider**section.)
