Can u give the best settings for 200 Client

SERVER :
Core i5-10400F
Ram 32GB
SSD NVME 1TB

Thanks for the post. It is not normal and there is some issue that is causing it. You need to check for error logs to find out the actual issue. The error logs you shared only tell about rate limiting issue and there are no logs related to DNS resolution errors. So, you need to check the logs further to find errors related to resolution.

If you have enabled "Ignore Resolver Error Logs" option in Setting > Logging section then disable that option so that these error logs are written to the log file to be seen.

For the rate limiting issue, you need to change the QPM options in the Settings > General section to either increase the limits or remove them if this DNS server is running in a private network.

Also, it is not clear how the DNS server is configured. Is it using any forwarders or doing recursive resolution?

[muhanadali100]

DNS SERVER running in private network

all setting are the default

I don't even know what DNS is So i need your help to configured it

Thanks for the details. The screenshot now shows 0.2% server failure rate which is quiet normal so it seems that the issue has been resolved. It could have been some transient network issue which got resolved.

For the QPM option, you can just use the "Delete" button to remove those entries to remove any rate limiting instead of setting the value to "0". That will work much better. Rest of the config looks fine.
