## Symptoms

- * SNX Portal does not work after Security Gateway upgrade - it allows login, but an error appears:  

  "`Cannot establish connection to SSL Network Extender gateway. Try to reconnect.`"

* There is a 3rd party certificate added in IPsec VPN blade.

* SNX Portal works as expected if all other portals are disabled (e.g., Identity Awareness Web Authentication Portal).

## Cause

IPSec VPN blade recognizes only ICA certificate.

Since IPSec VPN Blade does not recognizes the 3rd party certificate used, it rejects SNX connection that uses 3rd party certificate.
