So i am trying to run my VPS for a minecraft bungee network, everything is setup but after 2days the server got very laggy so i rebooted the whole VPS (not in rescue mode) and i got a email saying its gone into rescue mode. I havent changed anything at all and it was working perfectly!!!
Please help me as this is very annoying!

Error email:
ERROR: missing : /bin
ERROR: missing : /sbin
ERROR: /etc/passwd needs 'read' permission
ERROR: /etc/shadow needs 'read' permission
ERROR: /usr/bin/passwd needs 'execution' permission
ERROR: /sbin/init needs 'execution' permission

Thank you for helping me (i am also new to VPS's so if you can explain it in detail will be much appiciated!)
