今天遇到nginx NSS error -12263 (SSL_ERROR_RX_RECORD_TOO_LONG) 处理，简单记录一下：

• 端口要配置为支持ssl
• 不能同时ssl on及 listen port ssl

可以参考https://*.com/questions/20262186/error-code-ssl-error-rx-record-too-long-for-https-in-nginx-on-ruby-on-rails-app

You can’t have both listen 443 ssl; and ssl on;, remove the ssl on; line and restart nginx.

# HTTPS server
#
server {
    listen 443 ssl;
server_name welcome.com;

root html;
index index.html index.htm;

ssl on;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;

ssl_session_timeout 5m;
}
