Why are so many trackers comming up dead or rejected?

I was trying to work this out with MS Copilot as it's been pretty resourceful lately, but not on this.

I added two long lists of trackers from Gethub and I am getting good download speeds and a few uploads. But why are there so many trackers coming up N/A for peers, and rejected or terminated? Like out of 80 trackers there's like 6 or 7 working. The other thing that's odd is, you'll see a bunch of seeds on a magnet, but then you go to try it, and there's like 0 (1) or 0 (3) if you're lucky.

Extra Info
  • I'm using the Proton Port forwarding and it is active. I tried adding google and Cloudflare DNS address into Proton settings for a test.
  • Tried flushing DNS
  • My Windows firewalls has two rules, TCP/UDP allowing all ports for Inbound traffic that I think were added when i installed Proton. Seems to be working
  • Tried running OpenVPN TCP protocal instead of default just to see if the trackers changed
  • Tried a few different servers.
  • qBit settings are at default except I have PuP disabled and I'm forwarding the active port each time.
  • Tried DNS lookup tools like NsLookup.io to verify the DNS records for the trackers

Trackers don't need port forward and such, they are simple TCP connections like a webpage loading. The reason they go down is because... they go down.

- They are ran by regular people and it's hard to monitor them for quality. You can't really expect a public tracker to be 100% up for years.
- You absolutely can use this project to get a fresh and working list: https://github.com/ngosang/trackerslist
- But here is the problem. When .torrents are created, they include a list of trackers. These trackers are IN THE .torrent file and they do NOT change.
- Now you can see the problem. As time goes by, they go offline.

You have two ways to combat this:
- You can add new trackers to existing torrent files. You just grab the whole list from that project above and you can make qBittorrent auto-add them to new public torrents you load. HOWEVER THIS ONLY WORKS IF OTHER PEERS ALSO DO THIS.
- DHT and PeX exists to combat this. They work as a kind of "tracker-less" way to get new peers. But, these do require open connection/port forward which many also don't have.

Hope that clears things up.
