求助官方：
发现一个office预览一直转圈的问题
1-在用户空间、单独一个文档的共享这两种情况下，office预览完全正常
2-在共享目录链接下的office文档，点开会一直转圈圈，seahug.log 有报错日志
求助，请问是什么原因？
自己思考
怀疑在不同场景下Office文件预览服务的方法不同，造成了connection error，但不会排查。。。
有的朋友说是Libreoffice版本问题，都试过了，问题依旧
环境
seafile: 7.1.5 专业试用版
OS: Ubuntu 20.04
Python: 3.6.5 - 3.9 都试过
Libreoffice: 6.4-7.2 都试过
