Fortigate FG201F System DNS Servers Delay Issues

Hi All !

On my FG201F device dashboard, I see the status of "System DNS Servers" has unstable latency (sometimes very high). It seems to be affecting our network performance.

Note: This device is running firmware "v7.4.5 build2702 (Mature)" with 4 Internet lines (divided into 3 SD-WAN groups), the system is also divided into VLANs.

Could you please assist us in diagnosing this issue? Any guidance on potential configurations or troubleshooting steps would be greatly appreciated.

Thank you for support.
