Reached maximum failures querying DNS server

[spacemeb]

Hello,

We have multiple dns servers configured with different priority but still we have errors like that: 

Reached maximum failures querying DNS server 

It seems to be from DNS's side but still, do we have any options from WSA's side? What else should I do?

I tried to change the priorities for the beginning but it does not seem to work.

Thanks a lot!

how is your DNS Server config, do you have any priority ? if you have more than 1 DNS servers you need set as same same priority.

check GUI Network--> DNS (make sure all setup 0 priority)

Note : what version WSA, some OLD WSa have some bugs around

After changing the priority , try to clear DNS cache 

CLI > dnsflush  > Y 

what is your current WSA version?

kindly check these defects:
