401 error

[DevJoey]

I get this exception org.jsoup.HttpStatusException: HTTP error fetching URL. Status=401, URL=https://www.patreon.com/api/oauth2/token at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:682) at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:629) at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:261) at org.jsoup.helper.HttpConnection.post(HttpConnection.java:256) at com.patreon.PatreonOAuth.getTokens(PatreonOAuth.java:57) at net.proxysocke.gittest.LoadUp.main(LoadUp.java:34)

my code public static String clientid = "sec"; public static String clientsecret = "sec"; public static String redirectUri = "my url";

public static String code = "code";

public static void main(String[] args) {
	
	try {
		PatreonOAuth authClient = new PatreonOAuth(clientid, clientsecret, redirectUri);
		PatreonOAuth.TokensResponse tok = authClient.getTokens(code);
		
		
	} catch (Exception e) {
		e.printStackTrace();
	}

} }
