DNS Troubleshooting

I am running the latest XG release and am finding that sometimes DNS resolution is stopping. The Firewall is responsible for DNS requests. The problem tends to go away on its own by just waiting or I can force it by restarting the DNS service. Any suggestions for what to look at to troubleshoot when this next occurs?

Do you configure different DNS forwarders? Your-ISP-DNS / 1.1.1.1 / 8.8.8.8 ? Some other (ISP-DNS) don't answer sometimes; if you come from different ISP.

Yes I did configure DNS forwarders. DNS is normally working just fine. Moments ago - it stopped working until i restarted the DNS service.
