Hi, we’re getting random SSL_write() failed errors on seemingly legitimate requests. The common denominator seems to be they are all for static files (images, js, etc.).
Can anyone help me debug the issue? Here’s a debug log paste for one incident: https://pastebin.com/ZsbLuD5N Our architecture is: Amazon ALB > Nginx 1.14 > PHP-FPM 7.3 Some of our possibly relevant nginx config parameters: upstream php73 { server unix:/run/php/php7.3-fpm.sock max_fails=20 fail_timeout=60; } ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:20m; ssl_session_timeout 120m; ssl_dhparam /etc/nginx/dhparam.pem; ssl_ciphers !aNULL:!eNULL:FIPS@STRENGTH; # http://blog.chrismeller.com/configuring-and-optimizing-php-fpm-and-nginx-on-ubuntu-or-debian # Caching configuration using 30 days expiration delay for static served files. location ~ \.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpe?g|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf|cur)$ { set $location_name static; # Location name expires 30d; log_not_found off; access_log off; } _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
