Error: Seat reservation expired

[zack1991]

Hi,

I am trying to scale the colyseus process on multiple instance of server but i am getting seat reservation expired error. I am sharing my code and logs.

Nginx loadbalancer -

upstream sw_nodes {
    server <My Server IP>:1531;
    server <My Server IP>:1532;
}

server {
	listen 80 default_server;
	listen [::]:80 default_server;

	root /var/www/html;

	# Add index.php to the list if you are using PHP
	index index.html index.htm index.nginx-debian.html;

	server_name _;
	
	location /sw-server/ {
		proxy_pass http://sw_nodes; #upstream of nginx
       		proxy_http_version 1.1;
        	proxy_set_header Upgrade $http_upgrade;
        	proxy_set_header Connection 'upgrade';
        	proxy_set_header Host $host;
	}

	location /sw-server-1/ {
                proxy_pass http://<My Server IP>:1531;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
        }

	location /sw-server-2/ {
                proxy_pass http://<My Server IP>:1532;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
        }
}

My Server Code -

const RedisOptions = {
    host: process.env.REDIST_SERVER_HOST,
    post: process.env.REDIST_SERVER_PORT,
    password: process.env.REDIS_SERVER_PASSWORD,
    db: process.env.REDIS_SERVER_DB,
};
const nodeAppInstance = Number(process.env.NODE_APP_INSTANCE);
console.log(`nodeAppInstance => ${nodeAppInstance}`);
const PORT = Number(process.env.PORT) + nodeAppInstance;
const server = http.createServer(app);
const gameServer = new Server({
    presence: new RedisPresence(RedisOptions),
    driver: new RedisDriver(RedisOptions),
    transport: new WebSocketTransport({
        server // provide the custom server for `WebSocketTransport`
    }),
    publicAddress: `My Server IP/sw-server-${nodeAppInstance}`
});
gameServer.listen(PORT);

Node Version - 14

Please anyone help what i am doing wrong. I will be thank full.

Thanks

upstream sw_nodes {
    ip_hash;
    server <My Server IP>:1531;
    server <My Server IP>:1532;
}

Maybe this ip_hash can fix your issue.

hello, were you able to fix this? I'm having the same problem

[icegriffinguru]

Hello.
I've deployed my Colyseus server on Colyseus Cloud and I'm facing the same issue even I set seat reservation time to 1 minute.
Can anyone resolve the issue?
