issues connecting to seeds/peers

Post by hazardass »

Very often (not always) I would try downloading a torrent which has at least several seeds, but my client would only connect to 1 or 2, and sometimes none.  What could be causing this?  Is it a setting on their end?

What's even weirder is that recently, a friend of mine (from another country) who is also using qB, started downloading a torrent which I am seeding, but for a long time we did not connect.  For many days he was only connected to 1 or 2 other seeds, downloading at suboptimal speeds.  My qB was relatively inactive, so its not like I had reached some maximum number of connections or anything.  I had almost nothing happening in qB.  Why wouildn't qB connect me to him?  What could be possible reasons?

Only when he reached about 90% of the rather large torrent, we got connected and I was transferring to him (I saw him in the peers list). 

For some reason the torrent network is not optimally utilized.  Is this a client issue, protocol issue, or what? 
When I don't connect to seeds, I tend to think it's something on their end.  But when I know for a fact that someone is downloading at low speeds something that I am trying to seed, and its not connecting us, then I know something must be wrong. 
I have my qB port forwarded and I pass a port check.  Win 7 x64, qB 4.1.1

Any help would be appreciated.

Local firewalls and bad ISPs can also prevent peers connecting to each other.
Or 1 of the peers already having max connections on a torrent and not allowing others...even if many of its connections are "dead horse" peers+seeds that do nothing.
Or there may be torrent poisoners active on the torrent, flooding the swarm with 1000's of ip addresses that never work.

Beyond all that, there may be problems with qBitTorrent/libtorrent with regards to peers connecting to each other, going by what I've also seen using qBitTorrent versus using uTorrent (which seems better at connecting to peers).

Try manually adding the ip+port address of your friend on a less-busy torrent to see if that works.
