Okay, now that’s weird. I switched to “any interface” for what to bind to instead of my Ethernet interface and that somehow made torrenting work again?

I’m pretty sure it’s not ISP throttling but more some weird BitTorrent issue; how was aria2c able to saturate my connection while BitTorrent couldn’t move a single byte to save its life?

Is my VPS provider going to nuke me if I dare use my VPS as my VPN, though? Ionos, if it’s relevant…

Update: I was somehow able to torrent a different one with aria2c, and it went at full speed, so I’m very sure that I’m NOT being blocked by my ISP…
