Could you show how your connection string look like?

Does it work with localhost?

$cluster = new \Couchbase\Cluster("couchbase://127.0.0.1");
$bucket = $cluster->openBucket("default");

There is also tool for diagnosing Couchbase connections: https://github.com/couchbaselabs/sdk-doctor
Its output might have some clues about what might be wrong. Could you try to run it and paste output here? You can download pre-built binary for your platform here: https://github.com/couchbaselabs/sdk-doctor/releases
