the error: Error: Could not open HTTP connection. Connection error: yes in my localhost run, in hostgator, hostinger and others servers not run...

i'm Doing scrap torrents and taking the seeds of them, I use the script that I found on the internet and it uses socket to connect the tracker and get the data, it typically run on my localhost with xampp server but when it does not send pro server works, it does not catch the seeds of the stream and the script generates an error message the script: <?php /* Torrent UDP Scraper v1.2 2010 by Johannes Zinnau johannes@johnimedia.de Licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License http://creativecommons.org/licenses/by-sa/3.0/ It would be very nice if you send me your changes on this class, so that i can include them if they are improve it.
