Nginx refused to connect to port 443

So, I am trying make Nginx serve my website via https, but it keeps hitting me with a refused to connect error.

So here are the outputs for:

1. curl https://juristnet.ro (this is the website)

   curl: (7) Failed to connect to juristnet.ro port 443: Connection refused
   

2. netstat -anltp

As you can see, port 443 is open and Nginx is listening

80/tcp   open  http
443/tcp  open  https
3306/tcp open  mysql
5432/tcp open  postgresql

Nmap shows port is open.

UFW is inactive, so not firewall issues. It's a droplet at digitalocean, so no forwarding problems on their side.

3. iptables -L

My Nginx.conf:

My other conf ( for the server blocks):

}

There is also another subdomain, but i'm guessing that's not relevant.

The error logs and access logs for nginx don't show anything special.

The certificates were obtained from letsencrypt. If I try binding gunicorn
as it is on 0.0.0.0:8000, with the –keyfile and –certfile options, it does work with https, so I am guessing this is an nginx issue. Or maybe i need to add those settings somewhere? Anyway, I have been bashing my head on this for 2 days, so if anybody has any solution to this, I would be very thankful.
