seafile容器运行好好的，但突然不能正常访问，通过查看日志记录，发现出现如下错误提示：
Error:Seahub failed to start.
Please try to run “./seahub.sh start” again
waiting for mysql server to be ready: %s (2003, “Can’t connect to MySQL server on ‘db’ ([Errno 111] Connection refused)”)
Traceback (most recent call last):
File “/scripts/start.py”, line 95, in
main()
File “/scripts/start.py”, line 81, in main
call('{} start'.format(get_script('seahub.sh')))
File “/scripts/utils.py”, line 70, in call
return subprocess.check_call(*a, **kw)
File “/usr/lib/python3.10/subprocess.py”, line 369, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command ‘/opt/seafile/seafile-server-11.0.8/seahub.sh start’ returned non-zero exit status 1.
通过重启可以解决，但不知道是什么原因出现上述的错误信息，求指教，谢谢。
