错误提示：

“缺少所需的TLS 功能” 错误代码：MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSING

解决方案：编辑nginx.conf在server下添加SSL配置和加密：

ssl_protocols TLSv1.2 TLSv1.3;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_prefer_server_ciphers on;
ssl_ciphers 'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384';
ssl_stapling on;
ssl_stapling_verify on;
