Kulbir I have problem!!!
DEQUEUE_ERR - [Errno 104] Connection reset by peer
This is error from videocache.log
I use Bridged network and TPROXY with Squid 3.1.1!!!!
I am sorry for the delayed response, but this is definitely because of the XMLRPC server. Its not working or its dead. Whenever you encounter these error, its good to reload the squid service and it'll automatically be fixed. This is very rare error if videocache was working properly previously.
