auto ws_url = URL("wss://stream.binance.com:9443/ws/ethbtc@aggTrade");
auto ws = connectWebSocket(ws_url);
if ( !ws.connected )
return;
sleep(2.seconds);
ws_url = URL("wss://stream.binance.com:9443/ws/iotabtc@depth");
ws = connectWebSocket(ws_url);
if ( !ws.connected )
return;
This is a minimized version of my case. The first connect is successful. But after second
connectWebSocket(ws_url); I sometimes recieve :
-object.Exception@../../.dub/packages/vibe-d-0.8.3/vibe-d/tls/vibe/stream/openssl.d(352): Reading from TLS stream was unsuccessful with ret 0

What I am missing here ? I really need to be able to two sockets at the same time.
