Torrents stalled Transmission 3.0

[thenerdyangel]

Following an SSD failure, I did a fresh install of Linux Mint.

I've connected the external drive where the torrent files are and opened them with Transmission. I did "set location" and "verify local data".

I'm using a new VPN provider, IVPN. Port forwarding is activated. Transmission says the port is opened.

The files are all with private trackers.

In the properties, in the tracker tab, I see the url of the tracker, list of x peers received x minutes ago. It seems fine.

But after a while, it will say "stalled". I don't seem to be seeding either. Before my SSD failure, I would pretty much always have something seeding.

I'm not sure what I'm doing wrong.

I have been able to change the config files so the torrents don't stall anymore, but I'm not seeding. It says the port is closed. I don't know what to do. Firewall is not on. Port forwarding is activated on IVPN. I've added a rule in my router's settings.
