## Symptoms

- User receives "Unreachable" message instead of a UserCheck page, when HTTPS Inspection is enabled and the gateway is configured as a proxy or the gateway is located between a client and a proxy.

## Cause

When HTTPS connection is tunneled through HTTP proxy, the client sends HTTP "CONNECT" request as a first message.

If the gateway tries to reply with UserCheck redirect to such message, the result will be: the "Unreachable" message in browser. This happen cause most browsers are not supporting redirect reply on CONNECT request.
