The remote party closed the WebSocket connection without completing the close handshake

Reported by @rakeshparihar on endel/NativeWebSocket#61

Using Reserve seat API to join in a room, and when there is a WebSocket connection drops unexpectedly, its not reconnecting and getting an error " The remote party closed the WebSocket connection without completing the close handshake." with error code : 1006.

Step to reproduce:

Join room by Seat reserve call - (Independent of matchmaking of Colyseus)

• After successful seat reserve call
• Ping pong should be started
• Once get connected try to close the internet for a few seconds or if your internet gets disconnected for some reason.
• you will get the issue right there

Hi Any update on this issue? even we are also facing the same issue

Hi, I am facing the same issue as well. Using an android build to test
Steps :

• User disconnects internet on their device.
• pingInterval: 15 and pingMaxRetries: 1. The server waits accordingly for that time and players are also shown in colyseus monitor panel.
• However, on the client, the device's websocket connection is closed and abnormal code 1006 is thrown.
• Client is unable to reconnect to the server and room, even though the server hasn't removed the player from the room (as seen in monitor panel)

PS: in the server's onLeave method, have added code to allow for reconnection

@AbhishekFYND Do you possibly have a small project where we can observe this problem? Do you also use the reconnection feature?

@nuruddinwarsi How does your onLeave() method look like? I've seen some people using .allowReconnection() without the await keyword, thus having unexpected behaviour

@endel

try {
if (consented) {
throw new Error(Player ${leavingPlayer.id} consented );
}
// 10 sec allowed to reconnect
await this.allowReconnection(client, GameRules.ReconnectionTime);
leavingPlayer.assign({
connected: true,
readyState: PlayerReadyState.READY,
});
} catch (ex) {
// code to remove player from state and declare winner
}

I have few concerns regarding my connection flow as well.
Server is using typescript / Node and client using Unity / C#

• Instead of using joinById / create room from client side, I am using the match maker API to create seat reservation.
• Send the seat reservation data to client using a middleware android app, which passes the data to unity client
• The client then uses the consumeSeatReservation method

Is there a difference between using client side vs server side joinById method?
