Eventstoredb: Cannot connect to cluster (3 nodes)

I am having trouble connecting to eventstore cluster (with 3 nodes). So I have a 3 nodes each running on Azure VM and below is the code to connect and append streams

var settings = EventStoreClientSettings.Create("esdb://admin:changeit@{node1IP}:2113,{node2IP}:2113,{node3IP}:2113?tls=true&tlsVerifyCert=false&keepAliveTimeout=10000&keepAliveInterval=10000");

var client = new EventStoreClient(settings);
                
var evt = new 
{
    EntityId = Guid.NewGuid().ToString("N"),
    mportantData = "I wrote my first event!"
};
                
var eventData = new EventData(
    uid.NewUuid(),
    "TestEvent",
    JsonSerializer.SerializeToUtf8Bytes(evt)
);
                
await client.AppendToStreamAsync(
    "some-stream",
    StreamRevision.None, 
    new[] { eventData });
                
var result = client.ReadStreamAsync(
    Direction.Forwards,
    "some-stream",
    StreamPosition.Start);
                
var events = await result.ToListAsync();
foreach (var eventIn in events)
{
    Console.WriteLine($"event: {eventIn.ToString()}\n");
}

Error I am getting is DiscoveryException: Failed to discover candidate in 10 attempts.

I can telnet the address from my local machine and seems to the problem is only with gRPC connection.

server config for one of the node, other 2 looks pretty much same except for the ip changes.
