So I spend the entire morning trying to solve this. I'm having port issue.
My first concern was with NordVPN, I first set this settings to match NordVPN advices :

Nothing happened. Then I understood that proxy is just for hiding identity (correct me if I'm wrong) and found in this forum that NordVPN does not allow port forward so I turned NordVPN off.
I then tried to set my router properly, using Static IP first :

setting then in my router :

opened forwarded ports like this :

and this :

Reboot my router but nothing works. I finally checked if everything's fine with windows firewall :

As you can see, seems good.
So, i feel lost, I don't get it. It's been a while I didn't use deluge, I haven't any trouble before using NordVPN (I'm using v2.1.1 of deluge by the way), I didn't changed any settings before today. So what's wrong ?
Just to avoid time lost for you, here are the main settings in deluge :





Hope that U guys can drive me to troubleshooting this !
Have a great day !
