Stream end encountered

[starlight173]

Sometime I get disconnect issue because of stream end encountered error.

didCloseWithCode 1001, reason: Optional("Stream end encountered")
StompClientDidDisconnect

The server is still in operation. I think this comes from SocketRocket. Do you have any idea about this issue?

This is NGiNX issue.

Always facing this issue. Automatic disconnected after 30-40 seconds

didCloseWithCode 1001, reason: Optional("Stream end encountered")
StompClientDidDisconnect

@SSUS31 Maybe @gloryluu will tell you how did he/she fix the problem. This is not related to StompClientLib.

As I remember, it related to the heart beat. Workaround is to ping pong the server every 30s to maintain the connection

[SSUS31]

Can you show please how to do it.
@WrathChaos, didn't you face this kind of ping or heart-beat issue?

[starlight173]

There're 2 ways to fix in my situation, either:
1/ You put a timer for every 30s to send a ping command to server. Check in the lib source you will see how he handled it:

socket?.send(StompCommands.commandPing)

or

2/ You ask server to send you a ping ( heartbeat - built in config) and let the lib handle over all for you.

Hi @gloryluu, how did you ping the server using this library? I can't seem to find out how to do this.

i called this with a Timer for every 20 seconds
self.socketClient.openSocketWithURLRequest(request: NSURLRequest(url: url as URL), delegate: self as StompClientLibDelegate, connectionHeaders: ["Authorization" : "Bearer xyz)", "heart-beat": "0,10000"])

Oh, I see, that works thank you. Another thing I tried is calling socket client.openSocketWithURLRequest(...) only when stompClientDidDisconnect(client: StompClientLib!) is called. However, there is a chance you might miss a message. So I make sure to verify the status with our backend whenever it reconnects.

In my case calling it every 20 seconds seems inefficient as the backend doesn't kick us out, (i.e socket disconnects) until after a long time (usually over a minute). So I only try to reconnect when the socket disconnects.
