Seeders Dissappear When Using Anonymous VPN #9495
Please provide the following information
qBittorrent version and Operating System
If on linux, libtorrent and Qt version
What is the problem
When downloading a torrent without a VPN connection there are many seeders. When an anonymous VPN connection is established most, if not all, seeders disappear. Most of the time there are no seeders with VPN.
What is the expected behavior
Number of seeders should be the same with or without a VPN connection.
Steps to reproduce
Start downloading a torrent. When more than 0 available seeders is confirmed, establish a VPN connection.
Extra info(if any)
Since this forum question has received no responses I am guessing it must be a bug perhaps related specifically to the CentOS 7 implementation of qBittorrent.
Some seeders may only work using uTP, which uses UDP packets that VPNs may not support well - and some proxies won't support at all.
There are likely bugs in qBitTorrent/libtorrent as well that can prevent connections...likewise the destination seeds may also have other connectivity problems and/or be running buggy BitTorrent.software.
More precise testing of qBT needs to be done (such as on a LAN and even local loopback on 1 computer) to rule out all the possibilities to narrow down whether this is a bug with qBT, the VPN, or other issues are involved.
