Some guy here deployed EE and setup wildcard by for us, it works well for several months.

But since last week, it suddenly show ERROR at frontend: "SSL_ERROR_NO_CYPHER_OVERLAP "

I am quite confused by this issue since we did not touch the server end.

Here are some improper information after I test our domain at:





So, What might be the reason please?



it seems nginx ciphers_suite isn’t up-to-date anymore. You can generate Nginx SSL/TLS configuration on

Then just edit them in /etc/nginx/nginx.conf.

An update with up to date and reasonable configuration required.

Hi @virtubox and @ashishdungdung,

Do you mean this part?

server { listen 80 default_server; listen [::]:80 default_server;

# Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
return 301 https://$host$request_uri;


server { listen 443 ssl http2; listen [::]:443 ssl http2;

# certs sent to the client in SERVER HELLO are concatenated in ssl_certificate
ssl_certificate /path/to/signed_cert_plus_intermediates;
ssl_certificate_key /path/to/private_key;
ssl_session_timeout 1d;
ssl_session_cache shared:SSL:50m;
ssl_session_tickets off;

# Diffie-Hellman parameter for DHE ciphersuites, recommended 2048 bits
ssl_dhparam /path/to/dhparam.pem;

# intermediate configuration. tweak to your needs.
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;

# HSTS (ngx_http_headers_module is required) (15768000 seconds = 6 months)
add_header Strict-Transport-Security max-age=15768000;

# OCSP Stapling ---
# fetch OCSP records from URL in ssl_certificate and cache them
ssl_stapling on;
ssl_stapling_verify on;

## verify chain of trust of OCSP response using Root CA and Intermediate certs
ssl_trusted_certificate /path/to/root_CA_cert_plus_intermediates;

resolver <IP DNS resolver>;



Great thanks.:slight_smile:
