Using API or their chat.deepseek.com? I just get this:

You can seed, it’s just slow. It’ll only connect to other users that have closed ports. With ports open, it’ll connect to both, but as said not possible with Mullvad with port forwarding disabled. That’s at least as far as I know

Unrelated, but I find it weird that DeepSeek refuses to tell me about Socialism with Chinese Characteristics. It will auto-delete / block the message it’s trying to reply with. Does this also happen for you? Like “Can you explain Socialism with Chinese Characteristics for me?”.
