我自行部署的seafile服务端指定了非常用端口，然后在客户端访问的时候可以正常连接和获取资料库，也可以正常下载，但是在同步的时候一直不能进行，查看问题日志发现：

不知道这个是不是同步的过程，但是这里请求的时候确实没有带上我配置的端口号，而我自行添加了端口号后在浏览器中进行请求（seafile.my.in:[我的端口号]/seafhttp/protocol-version），返回是正常的。所以这里同步使用的url是配置问题还是在读取配置的时候不完整？
补充一些情况，我在服务器配置页的 SERVICE_URL 和 FILE_SERVER_ROOT 都配置了带端口号的 url 地址，客户端配置的url也带了端口号，唯一没有带端口号的url是 docker-compose 文件中的 SEAFILE_SERVER_HOSTNAME ，因为服务器配置页声明了配置页的属性有更高优先级
