Error during WebSocket handshake: Unexpected response code: 403

Using directLine or Webchat with my bot

After 5 minutes of using the bot i get a Websocket error.

If I let the chat window open everything is fine. When i close the chat windows and then reconnect to the conversation the websocket error appear and the history isn't comming back. The chat still work but if i close it again the history is not saved anymore to the conversation.

I used postman to lisen to the websocket stream and i can see everything pass. When I try to connect to a stream after 5 minutes(after the websocket error), i got this message

I tried to make a loop to send a message each 60 seconds on my website with a secondary direct line connection to the same credentials. I wanted to find out if it's en idle problem and it's not.

      this.mySubscription= interval(environment.webSocketPingDelay).subscribe((x =>{
            let directLine = window.WebChat.createDirectLine({
                token: this.storageService.token,
                webSocket: environment.payload.webSocket,
                conversationId: this.storageService.conversationId,
                streamUrl: this.storageService.streamUrl
            });

        directLine.postActivity({
            from: { id: Authentication.user, name: "USER_NAME" },
            name: "keep_alive",
            type: "message",
            Text: "Keep"
        }).subscribe();
      }));

Since the web socket address indicate that the websocket is hosted on azure. "wss://directline.botframework.com/v3/directline/conversations/***"

On my azure channel i see no option to configure websocket.

On my webapi i used this configuration in my startup.cs

var webSocketOptions = new WebSocketOptions()
{
KeepAliveInterval = TimeSpan.FromSeconds(120),
};

app.UseWebSockets(webSocketOptions);

How can i configure it to last more than 5 minutes ?
