Sorry, but the requested page is unavailable due to a server hiccup.

页面报错如下：
我再重启服务器之前做了备份数据库和数据文件夹操作
我把虚机快照到刚部署完成的状态，然后用官方教程恢复数据，恢复之后依然有这个报错。
请路过的大佬帮忙看下有么有办法解决。
这是服务器没有正常启动，你看一下服务器日志有没有什么报错？配置是否更改过？
不好意思，刚开始接触开发者版，麻烦问下这类问题主要看哪个日志文件

django.db.utils.OperationalError: (1049, "Unknown database 'dtable_db'")我直接将虚拟机恢复到之前正常状态的快照，重启后还是这个报错，是我的数据库有问题了吗
看起来是数据库的问题，dtable_db 未知数据库。你排查一下数据库是否正常运行，服务器和数据库是否正常连接？
我做了seatable开启自动启动，发现只要重启或者使用命令systemctl restart/start seatable启动seatable就会出现这个问题，感觉是自动启动脚本有啥问题。
我关闭了自动启动，使用
docker-compose up -d
docker exec -d seatable /shared/seatable/scripts/seatable.sh start
是没问题的
如果你执行 start.sh start 脚本是正常的，那可能时重启或者自动启动脚本的问题（重启或者自动启动脚本执行时，没有正常启动 dtable-db 数据库，造成无法访问）那你重启后，看一下 dtable-db 是否启动，对应 dtable-db 的进程正常吗
请教一下，如何看dtable-db是否启动和对应dtable-db是否正常，谢谢！
你在 docker 内部执行 lsof -i | grep dtable-db 看一下 dtable-db 的服务是否启动就行
你在 seatable/seatable-developer:latest 这个容器中执行一下 lsof 命名
mariadb 是数据库
