When server side SSL decides to 'passthrough' the traffic, it requests that the client side convert itself to 'passthrough' mode, but the client side SSL was already in a closing state (due to timeout).


Traffic disrupted while tmm restarts.


When both Proxy SSL and Proxy SSL Passthrough are enabled. Proxy SSL changes to passthrough mode, but the client side is closed or has timed out.



Fix Information
