For now @Administrators please check what is problem?

Looks as though the most secure way to do this is to ask the staff to reboot the VPS from the management panel.  

Here's another article about Ubuntu 16 reboot disconnect problems:

If you don't want to submit support requests when you need a reboot, maybe it would be better to use a different OS.  

As far as I can see after I read through the above discussions I found the following:

1. Ubuntu has issues after an update when the reboot is made on the user level.  Something happens that has an effect on the SSH and or Firewall configuration
2. Reboot is probably better on the management console level
3. If you don't have a management console, and don't want to have to submit support requests for reboots, then it may be an idea to use a different OS instead.

Are you using Ubuntu? or anyother operating system?Do you use ( apt-get update & apt-get upgrades ) update commands.As deanhills mentioned that this problem is in the ubuntu update.
