Hi guys! I've a problem with websockets, I'm quite a noob on the subject and I'm doing some tests with them. I run the echo websocket this way: ZnServer startDefaultOn: 8000. ZnServer default delegate: (ZnWebSocketDelegate handler: ZnWebSocketEchoHandler new). I tested it with with the chrome extension (https://chrome.google.com/webstore/detail/simple-websocket-client/pfdhoblngb...) that emulates a websocket client. If I point to the url ws://localhost:8000 everyting is fine BUT I want to test the websocket server via ngrok (https://ngrok.com/) and if I point the client to the ngrok url (i.e. ws://myurl.ngrok.io that maps localhost:8000) it happens a connection-closed after a while and I can't understand the cause, is there a timeout somewhere? I know that it is something related to Pharo (and not to ngrok) because if I implement a simple echo websocket served via websocketd (http://websocketd.com) the connection stays always active even if through ngrok. Can you help me please? TIA Davide -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
