I have a set of RCVR channels over the past few months that have been complaining AMQ9259 when talking to a specific customer.

This only happens when the client connects from a specific subnet that their Dev machines are on.

When the client turns off SSL the channels from the DEV machine come up w/o issue. When SSL is enabled we get AMQ9259, and evetually he times out and gets AMQ9209.

We have confirmed the SSL handshake is being sent. Is there something in a network VPN that could prevent the SSL handshake, but still allow the channels to come up w/o SSL? What else could it be

Not a network expert but...

Could be the packet size or MTU on the network. The initial data flow on an SSL channel is quite large, and may be blocked somewhere.

Does the channel ever connect in SSL mode? I'd rather suspect a bad SSL setup than a network problem. Remember, both ends have to match...
