First open the download failed URLs to see if the sites actually work. (right click > open url)
If the URLs open then its most likey your proxies or thread count. Lower your thread count first and see if you sell get the message.
If you do this and still get the message then it might be your proxies. Public proxies are not good at all. Try to get some private proxies. Shared private proxies are ok to use if you are on a budget. Dedicated private proxies are the best.
