[SR-Users] Error connecting via websockets

Hello,
Your WITH_WEBSOCKETS #define does not enable the XHTTP event_route. Even
if it did, you don't have any WebSocket handshake handling code within the
XHTTP event_route. Also, the WITH_WEBSOCKETS #define does not set the
tcp_accept_no_cl option that is required for XHTTP to work (and therefore
for WebSockets to work).
Once you have changed all that you still won't be able to route traffic
properly because you aren't using the nathelper module (or the outbound
module alternative) properly for WebSocket traffic.
You should take a look at the simple WebSocket example configuration in the
examples/websocket.cfg file in Git.
Regards,
Peter
