新部署的，网页端和客户端都能登录也能正常上传文件，但是客户端添加同步文件夹时不能同步，提示服务器内部错误，服务器版本是7.1.17，部署8.0.3也是一样的情况，之前用自动脚本部署没有这个问题，请问要怎么解决，如果要从日志找问题，要找哪个日志文件？
我查看了日志文件，感觉与elasticsearch有关，找到问题也不知道怎么解决
在controller.log这个文件中有一个报错，而且在/opt/seafile/pids/下面没有看到elasticsearch.pid这个文件。
[05/07/21 08:19:57] seafile-controller.c(585): pid file /opt/seafile/pids/elasticsearch.pid does not exist

然后再elasticsearch.log也有报错
