The probability is high, your torrent software version is banned.
You will need a different software then.
Read about transmission in this forum. Maybe this can solve
Can I ask a stupid question: how can I check the BitTorrent version installed on LS-WVL?
I chat with hd-bits.ro. They told me give them the name of torrrent client and version. They will put it in the tracker Whitelist so that I can use my NAS to download torrrents.
I really can not find way to check the version, even asking Google already!!!
Happy New Year!
