upstream timed out (110: Connection timed out) while reading response header from upstream
Nginx错误日志为:upstream timed out (110: Connection timed out) while reading response header from upstream
解决办法为在server字段里修改proxy_read_timeout的值，具体参考
- proxy_connect_timeout 300;
- proxy_read_timeout 300;
- proxy_send_timeout 300;
