In your torrent client, you are using an IP Filtering list. Either the address or possibly one of the subnet ranges that our tracker uses is on your list. Please ensure that the following IP address and subnets are NOT found within your IP Filter list:

77.247.179.58
77.247.179.58/32
77.247.179.32/27
77.247.176.0/21

If you find ANY of the above in your IP Filter list, the connection to the tracker simply will NOT work until they are removed from the list, or the actual IP address itself is whitelisted and verified BEFORE looking through the hosts to block.
