Artalk XMPP: 'Authentication failed' message but credentials are valid-CodePudding

I set up an Openfire server (v4.6.6) and created a test user. I can login as the test user with both Spark (on Windows 10) and Xabber (on Android).

I'm trying to connect to the server with the Artalk.Xmpp:

using Artalk.Xmpp.Client;

var xmpp = new ArtalkXmppClient("143.#.#.133", "test@xmpp", "123", 5222, false);

try
{
    xmpp.Connect();
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}

I get "SaslException: SASL authentication failed." error message but as I said the credentials are valid and I can connect with other clients. What is the problem here?

Note 1: I don't have a domain so I have to use the IP of the server.

Note 2: I tried with another library (Sharp.Xmpp) and got the same error.

CodePudding user response：

Finally I solved the problem by changing the Domain name to be exactly as the IP address of the server (previously I set it to be xmpp) and then using test instead of test@xmpp as username.
