Unable to open a connection using Lucid Ocean C# Library

Mon, 12 Jul 2021 11:18:42 +0000

Good Day,

I am trying to work on a Hello world web application using LucidOcean.Multichain assembly using C# in Microsoft Visual Studio 2017. I am just trying to make a connection from the server to the server.

Following is my sample code taken from Multichain Developers website

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

MultiChainConnection connection = new MultiChainConnection()

{

Hostname = "xxx.xxx.xx.79",

Port = 7349,

Username = "multichainrpc",

Password = "F4oMLnguUvNYyT6ZUjKQY7r7auGCYzgB8NncZDdZS8QE",

ChainName = "ChainName",

BurnAddress = "1XXXXXXWzyXXXXXXg2XXXXXXcTXXXXXXXqFAPD",

RootNodeAddress = "1WNtXcjb8L9c96JnQbwsQKFPBxgnm1AJK5zd5F"

};

MultiChainClient _Client = new MultiChainClient(connection);

JsonRpcResponse<string> response= _Client.Wallet.GetNewAddress();

When I run the daemon command, resulting information gives me two ports to work with,

First port is 7349 given in the following lines

Other nodes can connect to this node using:
multichaind ChainName@169.254.88.79:7349

If I use 7349 as a port, code throws following exception

The underlying connection was closed: The connection was closed unexpectedly

Second port is 7348 taken from following lines

Listening for API requests on port 7348 (local only - see rpcallowip setting)

If use 7348 as a port, code throws following exception

Unable to connect to the remote server, No connection could be made because the target machine actively refused it 169.254.88.79:7348

Please advise what port I should use and what could be the problem prohibiting the connection?

I am trying to build an application with LucidOcean C# API, in the command line the mulitichain node is active.

I am not sure if I am doing it in the right way, I create a C# applicationi and try to connect to this multichain node by using methods from API.

Here is my code,

MultiChainConnection connection = new MultiChainConnection()
            {
                Hostname = "127.0.0.1",
                Port = 4336,
                Username = "multichainrpc",
                Password = "password",
                ChainName = "chain1",
                BurnAddress = "1XXXXXXXZXXXXXXXZMXXXXXXXqXXXXXXbYgmzH",
                RootNodeAddress = "1TXfbuQzKGpDbTsAEAxdi7ZK5aUYTEVicUKWYT"
            };
            _Client = new MultiChainClient(connection);

...

...

     public JsonRpcResponse<List<string>> GetAddressesAsync()
        {
            JsonRpcResponse<List<string>> response = null;
            Task.Run(async () =>
            {
                response = await _Client.Wallet.GetAddressesAsync();
            }).GetAwaiter().GetResult();

            ResponseLogger<List<string>>.Log(response);

            return response;
        }

...

...

First question is, am I doing it in a right way?

2nd, How do I know if RPC is connected to the node?

3rd, how to solve "Unexpected character encountered while parsing value: <. Path '', line 0, position 0."

Thanks a lot if anybody could help me a little.
