this helped me. php conf and nginx default file was wrong

try this: it worked for me after installing letsencrypt on centos 6 linux

server { listen 80 default_server; server_name {domain-name} ; return 301 https://$server_name$request_uri; }

server { listen 443 ssl http2; server_name {domain-name} ;

ssl on; ssl_certificate /etc/letsencrypt/live/{domain-name}/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/{domain-name}/privkey.pem; ssl_session_timeout 5m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers ‘EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH’; ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; location / { proxy_pass http://localhost:8080; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection ‘upgrade’; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } location /.well-known/acme-challenge/ { root /var/www/domainame; }

}

The last line acme challenge one is vital for generating your website page. .

nope, i just rebuild the droplet with same configuration (same droplet size, location)…

i never deleted the droplet by myself, but digitalocean does it from there side and gave me a new droplet with same configuration.
