In the below VPN log snppet, we can see that the Proxy Server  configuration and Logout Script configured are pushed once the user has established the VPN session.

Once the user has logged out from VPN plugin, the Logout script should get executed and clear the proxy server configuration from browser. Whereas  in the below log snippet, we can see that  the logout script has failed to launch with the error 2. Thus, the logout script has failed to execute and did not clear the proxy configuration from Client browser.
