HowTo Add HTTPS redirect for Perseus?

[sudoshi]

Here is my amended nginx server.docker.conf:

server {

        listen       88;
        listen  [::]:88;
        server_name  sandbox.acumenus.net;

        location /.well-known/acme-challenge/ {
                root /verify;
                default_type "text/plain";
        }

        location = /.well-known/acme-challenge/ {
                return 404;
		}

		# Redirect all other requests to HTTPS
		location / {
			return 301 https://$host:2443$request_uri;
		}
}
		
server {

        listen 2443 ssl;
        server_name  sandbox.acumenus.net;

        ssl_protocols           TLSv1.2 TLSv1.3;
		ssl_certificate /etc/letsencrypt/archive/sandbox.acumenus.net/fullchain2.pem; # path to your fullchain.pem
		ssl_certificate_key /etc/letsencrypt/archive/sandbox.acumenus.net/privkey2.pem; # path to your privkey.pem
		ssl_session_timeout     10m;

    location / {
		proxy_set_header            X-Real-IP $remote_addr;
		proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header            X-Forwarded-Proto $scheme;
		proxy_set_header            Host $host;
		proxy_pass                  http://172.17.0.1:4200;
		# proxy_pass                  http://host.docker.internal:4200;

	}

Connects insecure on port 88
Connection refused on port 2443

Any ideas what I might be doing wrong here? Any help would be greatly appreciated.
