Cron suddenly doesnt work

[benlauwork]

My Vestacp are stable previously.
However, I suddenly receive these error messages yesterday and it is still continue to send me error message per 5 mins.
How to solve this problem?

Code: Select all

Cron <admin@mydomain> sudo /usr/local/vesta/bin/v-update-sys-rrd
sudo: unable to resolve host mydomain.org

Cron <admin@mydomain> sudo /usr/local/vesta/bin/v-update-sys-queue backup
sudo: unable to resolve host mydomain.org

I have checked the DNS of the domain and its nameserver still links to vps. How to solve this problem?

Thanks!

so you can do a "ping mydomain.org" and you will receive a correct answer (a record and replys to your icmp request)?
