Greetings everybody, I'm having issue connecting to the FirstSpirit server using the FirstSpirit Access API, namely I cannot seem to connect to one project because I keep getting the 504 status code back from the server more precisely this is the error:

Connecting to: "here was url of the server" on port: 443 as m.civcic

This is my class for connecting to a project:

public class Launcher {

    public static void main(String[] args) {
        connect();
    }

    /**
     * Method that connects to the First Spirit project
     */
    public static void connect() {
        final Connection connection = ConnectionManager.getConnection(HOST, PORT, MODE, USERNAME, PASS);
        ConnectionManager.setUseHttps(true);

        try {
            System.out.println("Connecting to: " + HOST + " on port: " + PORT + " as " + USERNAME);
            connection.connect();
            System.out.println("Connected.");

            SpecialistsBroker broker = connection.getBroker();
            final BrokerAgent brokerAgent = broker.requestSpecialist(BrokerAgent.TYPE);
            assert brokerAgent != null;
            broker = brokerAgent.getBrokerByProjectName(PROJECT_NAME);

        } catch (IOException | MaximumNumberOfSessionsExceededException e) {
            System.out.println("Connection failed.");
            e.printStackTrace();
        } catch (AuthenticationException e) {
            System.out.println("Wrong username or password! Please check your credentials and start the application again.");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                connection.close();
                System.out.println("Connection closed.");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
