Timeout error using the PHP extension

PHP SDK

I am running Community Edition 6.0.0, PHP 7.3 and PHP SDK 2.6.0.
Freshly installed Couchbase on Ubuntu 16.04
sdk-doctor gives OK from my PHP-server:

However, when running the example from the documentation:

$bucketName = "limelayer";

// Establish username and password for bucket-access
$authenticator = new \Couchbase\PasswordAuthenticator();
$authenticator->username('limelayer')->password('xxxxxxx');

// Connect to Couchbase Server
$cluster = new CouchbaseCluster("couchbase://10.0.0.109");

// Authenticate, then open bucket
$cluster->authenticate($authenticator);
$bucket = $cluster->openBucket($bucketName);

// Store a document
echo "Storing u:king_arthur\n";

$result = $bucket->upsert('u:king_arthur', array(
"email" => "kingarthur@couchbase.com",
"interests" => array("African Swallows")
));

var_dump($result);

Gives timeout error:

Storing u:king_arthur
<br />
<b>Fatal error</b>:  Uncaught Couchbase\Exception: LCB_ETIMEDOUT: Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout in /opt/www/limelayer.com/api/commands/get.php:20

If I change the password, I get authentication error, so I see that it reaches the server. It’s only when I try to do a write I get the timeout error. Any ideas?

Hey @daniele,

Would you be able to enable logging so we can get an idea of what the underlying problem might be here? You can refer to this URL for more information on how you might do that: https://docs.couchbase.com/php-sdk/2.6/collecting-information-and-logging.html

Cheers, Brett
