通过Nginx Proxy Manager反代访问calibre-web不能登录和搜索

在通过Nginx Proxy Manager反代访问calibre-web时，如果只做了默认设置，没有添加相应的参数，虽然能够正常打开calibre-web的首页，但是不能登录，也不能正常的搜索，需要在Nginx Proxy Manager的advanced里面添加如下代码：

location / { 
proxy_pass http://192.168.2.107:8086/; 
proxy_set_header Host $http_host; 
proxy_redirect http:// https://; 
proxy_set_header X-Forwarded-Host $http_host; 
proxy_set_header X-Forwarded-Port $server_port; 
proxy_set_header X-Forwarded-Proto $scheme; 
proxy_set_header X-Forwarded-Scheme $scheme; 
proxy_set_header X-Real-IP $remote_addr; 
proxy_set_header X-Forwarded-For $remote_addr; 
proxy_set_header Upgrade $http_upgrade; 
proxy_set_header Connection $http_connection; 
proxy_http_version 1.1; 
}
