[Pdns-users] How to set up pdns recursor to repeat the query if it does not get an answer

[Mira Krejci]

Hi,

I have a problem that I can't force the pdns recursor to query the
authoritative servers repeatedly if they do not answer. Recursor tries
the query only once and then return an error (SERVFAIL) to the client.
This is very problematic when the authoritative server is overloaded or
there are some problems on the network. I didn't find any way in the
configuration to change it.

Server version: 4.2.2-1 (from EPEL repo on CentOS 8)

Can anyone help?
Thanks.

Mira
