No website accessible after VM restore


i had to restore a VM from backup with a two-day old backup. After restoring I can’t access any of the websites I have hosted on the server including the Webmin Admin Site. E-Mailing is not working either.

I do not get any respsonse.

I use CentOS 7 and latest Webmin.

The webmin service is up. I also did reboot the server and restarted the services. But i get no response from the webservice.
