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

I have read about scalabily from this https://docs.colyseus.io/scalability/#step-2-making-your-colyseus-processes-accessible-to-the-internet and also refrence provided in this https://github.com/orgs/colyseus/discussions/578#discussioncomment-6174564.

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.

[CristianMFranco]

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?

I also experiencing this Seat reservation expired error

Using AWS Cloudformation, I deployed my colyseus server on ECS Fargate with Redis on ElasticCache and ALB.

This only happens on Matchmaking room and if it has multiple instance. But when running in single instance of ECS Task all working fine.

Instances must be directly accessible so the client can connect to them directly https://deploy-preview-163--colyseus-docs.netlify.app/deployment/scalability
