I just replaced WebSocket with SecureWebsocket Class in my project and I get: Conneting to WS server at: wss://xx.xx.xxx.xxx:8888/ws WSHEnandler: WebSockets internal error (java.lang.NullPointerException) Disconnected from WS server: WebSockets internal error (java.lang.NullPointerException) the: WebSockets internal error (java.lang.NullPointerException) comes form ws_Closed event

D daemon Active Member Licensed User Longtime User Oct 26, 2014 #8 Tried debugging a little bit, found that the WebSocket library uses SSLCertificateSocketFactory to create a socket, which seems to return a closed socket for such conditions: https://github.com/palmerc/SecureWe...avendo/autobahn/WebSocketConnection.java#L484 This results in NullPointerException at: https://github.com/palmerc/SecureWe...de/tavendo/autobahn/WebSocketWriter.java#L382 And the WebSocket library calls onClose() on any exception with Reason set to details.
