I am new to Box and using the example from https://github.com/box/box-java-sdk Below is the Java source code and the full error messages after it runs in my office computer with company network, but the same Java code works fine in my home network. It might be the issue of the company firewall. I just want to check if there is any idea or work around. Again, I very appreciate any kind help on this.
public static void main(String[] args) {
BoxAPIConnection api = new BoxAPIConnection("rX9DI8OHvikiLJigQbEbdP8EnxzhV9J6");//("your-developer-token");
BoxFolder rootFolder = BoxFolder.getRootFolder(api);
for (BoxItem.Info itemInfo : rootFolder) {
System.out.format("[%s] %s\n", itemInfo.getID(), itemInfo.getName());
}
}
Exception in thread "main" com.box.sdk.BoxAPIException: Couldn't connect to the Box API due to a network error.
