PagerDuty Notification not working


I have a problems with Pagerduty test notification, when I want to send it I got the following error:
Failed to send test alert.: send notification to Pagerduty: Post “”: dial tcp: lookup on [dns server ip]:53: no such host

I have modified the /etc/resolve.conf the order of servers and always the same error message came up with different dns address.

Thank you for the help.

So your configured DNS servers can’t resolve it.

I suspect DNS wrong, this is why I try other ones. The strange things that the same DNS servers working with other Grafana server.
