在我的apache webdav服务器日志中，我一直收到这些401和405错误，我不知道是什么原因导致的。

相关的httpd.conf部分具有：

Listen 21028

LoadModule dav_module lib/httpd/modules/mod_dav.so
LoadModule dav_fs_module lib/httpd/modules/mod_dav_fs.so
LoadModule dav_lock_module lib/httpd/modules/mod_dav_lock.so

DavLockDB /usr/local/etc/httpd/webdavdb/davlock

<VirtualHost 192.168.1.2:21028>
    ServerName my.server.me
    ServerAlias my.server.me
    DocumentRoot /Volumes/E/apache/webdav
    <Directory /Volumes/E/apache/webdav>
        Dav On
        AuthType Digest
        AuthName "webdav"
        AuthUserFile /usr/local/etc/httpd/webdavdb/users.password
        Require valid-user
        Options Indexes FollowSymLinks
        AllowOverride None
    </Directory>
</VirtualHost>

这几个星期都运行良好，但由于某种原因，我不能弄清楚-没有修改配置或任何相关的机器-服务器不断吐出这些错误。
编辑：为了测试，我已经删除了Require valid-user指令，这“修复”了401问题（暂时）。然而，我仍然可以为任何使用MKCOL方法的请求获得405（参见上面的日志）。
Apache DAV服务器位于nginx反向代理之后。当我通过本地地址（192.168.1.2）和http直接连接到Apache服务器时，我 * 没有 * 得到这些错误。问题似乎出在nginx转发请求到Apache的方式上，但我不知道我的nginx.conf有什么问题：

server {
    server_name my.server.me;

    location / {
        proxy_pass http://192.168.1.2:12345;
    }

    location /robots.txt {
        return 200 "User-agent: *\nDisallow: /\n";
    }

    proxy_set_header Host              $host;
    proxy_set_header X-Real-IP         $remote_addr;
    proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-Host  $host;
    proxy_set_header X-Forwarded-Port  $server_port;

    listen 443 ssl; # managed by Certbot
    # SSL stuff
}

有什么想法吗？
