    Hello i tried to make Update Checker for my plugin..

    Here is my Main class (Only OnEnable):
    Code:
    @Override
public void onEnable() {
    if (getConfig().getBoolean("Updater") == true) {
        Updater updater = new Updater(this, 309885);
        try {
            if (updater.checkForUpdates()) {
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "=-=-=-=-=-=-=-=-=--=-=-=");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "[ChatSecurity] New update!");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "Download new version here:");
                getServer().getConsoleSender().sendMessage(ChatColor.LIGHT_PURPLE + "https://dev.bukkit.org/projects/chat-security/files");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "=-=-=-=-=-=-=-=-=--=-=-=");
            } else {
                getServer().getConsoleSender().sendMessage("[ChatSecurity] Plugin is up to date! - "
                                + getDescription().getVersion());
            }
        } catch (Exception e) {
            getLogger().info("Could not check for updates! Stacktrace:");
            e.printStackTrace();
        }
    }


    Here is my Updater class:
    Code:
    import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import org.bukkit.plugin.java.JavaPlugin;


public class Updater {

    private int project = 309885;
    private URL checkURL;
    private String newVersion = "";
    private JavaPlugin plugin;

    public Updater(JavaPlugin plugin, int projectID) {
        this.plugin = plugin;
        this.newVersion = plugin.getDescription().getVersion();
        this.project = projectID;
        try {
            this.checkURL = new URL(
                    "https://dev.bukkit.org/projects/chat-security/files/."+projectID);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
    }

    public int getProjectID() {
        return project;
    }

    public JavaPlugin getPlugin() {
        return plugin;
    }

    public String getLatestVersion() {
        return newVersion;
    }

    public String getResourceURL() {
        return "https://dev.bukkit.org/projects/chat-security/files/." + project;
    }

    public boolean checkForUpdates() throws Exception {
        URLConnection con = checkURL.openConnection();
        this.newVersion = new BufferedReader(new InputStreamReader(con.getInputStream()))
                .readLine();
        return !plugin.getDescription().getVersion().equals(newVersion);
    }
}

    Here is error what i get when i start server:

    Moved to correct section
    @Straiker123 Why does the link contain a project number when the URL already covers that?

    Umm
    I modified the code for this:

    Main class (Only OnEnable):
    Code:
    @Override
public void onEnable() {
    if (getConfig().getBoolean("Updater") == true) {
        Updater updater = new Updater(this);
        try {
            if (updater.checkForUpdates()) {
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "You are using an older version of ChatSecurity!");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "Download the newest version here:");
                getServer().getConsoleSender().sendMessage(ChatColor.LIGHT_PURPLE + "https://dev.bukkit.org/projects/chat-security/files");
                getServer().getConsoleSender().sendMessage(ChatColor.RED + "=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=");
            } else {
                getServer().getConsoleSender().sendMessage("[ChatSecurity] Plugin is up to date! - "
                                + getDescription().getVersion());
            }
        } catch (Exception e) {

    @Straiker123 My guess is that you need to set an user agent.

    @Straiker123 Web requests use user agents to determine what kind of client is connecting, firefox, chrome, custom stuff.
    You don't have that set, don't know what it defaults to, server doesn't like the default.
