SOLUTION (My post on that link)

AutoSSL is the problem,reinstall cwp(you don't have to reinstall new OS)

http://forum.centos-webpanel.com/ssl/auto-install-letsencrypt-broke-everything!!/

I had an issue today where it was time for a real restart. Sadly after the reboot everything was running but I was locked out. no ssh, ftp nothing at all. So using vps web consol my host ran

yum -y remove NetworkManager
and rebooted and it's all back to normal.

As stated by my host provider.

on centos 7 NetworkManager breaks the network.
I have removed it with:

Code: [Select]

yum -y remove NetworkManagerand rebooted your vps and it's all back to normal.

Hello

What does

Code: [Select]

yum -y remove NetworkManagerexactly do?

I have this error:

Code: [Select]

Failed to start CentOS Web Panel service (daemon).
Does it help?
