java.lang.IllegalStateException: Already connected(Discord JDA)

            URL uImg;
            File fImg = new File("img.png");
            try {
                uImg = new URL(msg.getAuthor().getAvatarUrl());
                URLConnection uc = uImg.openConnection();
                uc.connect();
                uc.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
                FileUtils.copyURLToFile(uImg, fImg);
            } catch (IOException e) {
                e.printStackTrace();

Since you are using JDA you can take advantage of the http client it uses:

OkHttpClient http = jda.getHttpClient(); // getHttpClient since JDA 4.0.0
Request req = new Request.Builder()
            .url(avatarUrl)
            .addHeader("User-Agent", "DiscordBot")
            .build();
try (Response r = http.newCall(req).execute();
     FileOutputStream fileOut = new FileOutputStream(file)) {
    r.body().byteStream().transferTo(fileOut); // transferTo since java 9
} catch (IOException e) {
    e.printStackTrace();
}
