That sounds likely.
How does your firewall decide to block this traffic?
Layer-7 filtering doesn't really work for SSL traffic, only for the
initial certificate exchange which is plain text.
And if it is just based on port numbers, why would it care what sort of
traffic flows on that port?

First ssl handshake message from client successfully goes to the server as I can see connection request in the xpra server logs.But client never gets the message back from server. Seems like firewall decides to block this. I set up xpra server on port 443 for testing this.
If I setup a https server on port 443 ... that is not blocked by firewall.Any idea what is going on? Or anyway to avoid getting ssl blocked?
