Lets Encrypt SSL Certificate Setup Issue

Is your hosting environment one where the hosting provider/account also has a firewall or allowed ports policy? In this case, does your DigitalOcean account have its own settings about what ports are permitted?

I would try:
openssl s_client -connect 127.0.0.1:443
and see which certificate it serves and which name is on that cert.
That may point you to where the web service is getting is config.

well then…
You may have to begin at the beginning.
nginx.conf

follow every include
review each line for possible typing errors:
like *.443, www-domain.tld

something doesn’t add up:
this shows nginx is listening on 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 21905/nginx
and this output showed no ciphers available:
openssl s_client -connect 127.0.0.1:443

I appreciate all the help I’ve had. I’m off to bed, but will be back tomorrow after beginning at the beginning! I will keep you updated if I work out whats going on. If I still can’t get it to work I might buy another droplet and start a server from scratch as I’ve spent and enormous amount of time trying to solve this.

I began looking at nginx.conf and worked my way through all the includes. Everything looks fine, but it is not working. I have given up on getting this to work on that server and will try on a clean installation.
Thank you all.
