Couchbase timeout when trying to get document outside the EC2 instance

Couchbase Server
1

Hi everyone.

I am facing a trouble with my Couchbase server EC2 instance.

The Couchbase server version is:
Community Edition 6.0.0 build 1693

Since Friday, 27 I am trying to get a document outside the EC2 instance but timeout always are happening. I already check if all ports are open and it’s ok.

I get the feedback of the connection as the code bellow:

this.couchbase = require('couchbase');
		this.cluster = new this.couchbase.Cluster('couchbase://db.hostname/');
		this.cluster.authenticate('name', 'password');
		this.bucket = this.cluster.openBucket('bucketname');
		this.bucket.operationTimeout = 120 * 1000;
		this.bucket.n1qlTimeout = 120 * 1000;

this.bucket.on('connect', function (err) {
			if (err){
				console.log("Error connecting: ", err)
			} else 
			console.log('Created database connection');
		});
		this.bucket.on('error', function(err) {
			console.log('CONNECTION ERROR:', err);
		});

but always when I run the GET DOCUMENT code, it not run outside the instance:

this.bucket.get(docId, function(err, res) {
				if (err){
					reject(err);
				} else{
					resolve(res.value);
				}
			})

All the comands works very well in localhost.

Anyone knows how can I solve it?

Thanks for all help
