UDM Pro - DNS filtering slowing network to a crawl

Hello, 

 

We are experiencing extremely slow speeds using the next DNS filtering service at one particular site. We use the service at approximately 25 sites with no issue. We have verified the firewall settings match exactly to the 25 other sites that are working correctly. When we enable the DNS addresses for the network that point the next d&s the network slows to a crawl. When we disable it, it works on. We have attempted this four or five times to verify that next DNS DNS addresses are in fact the problem. Please advise and thank you.
