问题描述 / Describe Bugs

自己使用docker搭建的reader服务器，使用其自带的webdav作为书库。经过nginx反向代理为子目录访问，访问链接为https://test.com:1122/dav/。可以正常备份和恢复，本地书籍或缓存好的书籍可以正常导入至webdav。在远程书籍中也能够看到目录下的书籍，但是从远程书籍导入时失败，日志显示导入出错，timeout。查看nginx日志，access.log中只有一条记录"PROPFIND /dav/reader3/webdav/legado/books HTTP/1.1" 207 22862 "-" "Chrome/119.0.0.0 Safari/537.36 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)"。error.log中无任何记录。当代理为location /{}时情况一样。

我的nginx设置为：
server {
#添加加ssl和http2协议的要求。
listen 11loca22 ssl ; #ipv4
#修改为自己申请的域名
server_name test.com;
###添加秘钥

No source file or test is identified in the report. Reproduce remote-book import through the nginx /dav/ reverse proxy, then inspect the PROPFIND request and client timeout behavior against the provided access and error logs; done means remote books import successfully without timing out under the reported configuration.
