When using Web Traffic Redirection (WTR), end users occasionally receive an HTTP 407 response from Web Security Service (WSS) in the web browser. Expected behavior is that when a 407 response is sent down to the Symantec Endpoint Protection (SEP) client it is handled gracefully and triggers a re-authorization without the end user noticing.
Microsoft Windows
This issue is resolved in WTR Engine content build 1.1.0.272, available via LiveUpdate.
