我正在使用Nginx作为文件服务器/提供* .mpd / * .mp4文件的媒体服务器。服务器随机给出错误404（找不到文件），但是磁盘上存在文件。
这是我的nginx配置：
server {
listen 443 ssl http2 backlog=8192;
listen [::]:443 ssl http2;
keepalive_timeout 70;
add_header Access-Control-Allow-Origin *;
add_header Strict-Transport-Security "max-age=31536000; includeSubdomains";
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';

ssl_session_cache shared:SSL:10m;

location / {

sendfile on;
sendfile_max_chunk 2m;

tcp_nodelay on;
keepalive_timeout 65;
autoindex on;
}
location ^~ /.well-known/acme-challenge/ {
default_type "text/plain";
root /etc/letsencrypt;
}
}
我使用autoindex off和以下选项进行了尝试，但结果仍然相同：
location / {
mp4;
mp4_buffer_size 4M;
mp4_max_buffer_size 10M;
open_file_cache off;
alias /data/media/;
autoindex on;
}
MPD和MP4文件由Shaka Packager制作（直播电视）。我发现重启Nginx很有帮助，但这并不是一个很好的解决方案，因为正如我所说，这是直播电视。请问有人有类似的经历吗，还是有人知道如何解决？
谢谢！
