Some people have years of experience playing with public trackers and simple private tracker, but that's not enough to go further with high-class Private trackers. Offers from public trackers are attractive with HitnRun, no register requires, no maintaining ratio or upload to keep. Leechers could exchange for enormous GB upload by soft point system from simple private trackers. Private trackers demand higher standards, so tighter rules of torrent clients, some with no registration, point systems to exchange. If one decides to step into the dungeons of those trackers, they must have some following key preparation: client check (validation, port-forwarding, down/upload speed), read FAQ and tracker Rules in detail, ask for help as soon as you could, and DO NOT give up.
I asked for Bitspyder Invite weeks ago, and meet most the mistakes listed above. The ex-clients is Azureus/Vuze, and the customization is more than enough with Hdvnbits/TorViet, HD-Space, countless other public ones; then failed. Buying a mistake with a massive size torrent on Bitspyder, which has no bonus point system that I prefer, a lovely red warning size had appeared next to my username for days. Though uploads some of mine e-learning material up there, the ration is still some eggs. I rushed for any help, asked Bitsypder staff, read read and re-read, but still the Magikarp action. Finally, I found out, Bitspyder does not support the Blue Frog client.
Thanks to @Ulquiorra advice, Qbittorrent client replaced the old one. The 'No Connectable' on Bitspyder hasn't changed, but the upload has already improved greatly. My port-forwarding makes the download speed faster and hence the disappear of Bitspyder warning.
Many thanks.

If you find the similar issues, please let me know so we could exchange,
Or if you have better experience to deal with the situation, please comment to help other leechers, who start to play with high-class Private traders also.
