performOnMasterOnly property doesn't seem to work

Hi

I'am trying to create a persistent subscription to a eventstore cluster version 21.10.5. I've set the performOnMasterOnly property but it only tries to connect to follower nodes not to the leader node. The ClusterDnsEndPointDiscoverer always returns the first node it encounters and not the master node. Below is my client config.

$userCredentials = new UserCredentials($username, $password);
$connectionSettings = ConnectionSettings::create()
    ->setDefaultUserCredentials($userCredentials)
    ->useSslConnection($host, $useSsl)
    ->enableVerboseLogging()
    ->performOnMasterOnly()
    ->build();

$connection = EventStoreConnectionFactory::createFromConnectionString($connectionString, $connectionSettings);

Loop::run( function () use ($connection) {
    yield $connection->connectAsync();
    yield $connection->connectToPersistentSubscriptionAsync(
        'stream-id',
        'subscription-name',
        Closure::fromCallable(static function (EventStorePersistentSubscription $subscription, ResolvedEvent $resolvedEvent): Promise {
            echo 'received event!';
            return new Success();
        }),
        Closure::fromCallable(static function (EventStorePersistentSubscription $subscription, SubscriptionDropReason $reason, Throwable $throwable = null): void {
            echo 'subscription dropped.';
        }),
        1,
        true 
    );
} );

Thanks

Please paste your connection string

This is my connection string: GossipSeeds=<clusterId>-0.mesdb.eventstore.cloud:2113,<clusterId>-1.mesdb.eventstore.cloud:2113,<clusterId>-2.mesdb.eventstore.cloud:2113;UseSslConnection=true

Is also tried with the RequireMaster=true but have the same problem.

I try to get to it this weekend.

RequireMaster=true only has an effect upon appending events to a stream, not upon connecting. Try using preferRandomNode on the ClusterSettings and you should be able to connect to a random node.
