- Required: no
- Default: true on Windows, MacOS and Linux.
### nrpt_recovery_max_attempts
Windows DNS intercept mode uses NRPT health probes and recovery when Windows stops routing queries to the local `ctrld` listener. This limits how many consecutive recovery flows can run before `ctrld` enters a cooldown and stops making policy/Dnscache changes.
Set to `0` to disable this circuit breaker and keep retrying indefinitely.
- Type: integer
- Required: no
- Default: 0 (unlimited, current behavior)
### nrpt_recovery_cooldown
Cooldown duration after `nrpt_recovery_max_attempts` consecutive Windows NRPT recovery flows. During cooldown, `ctrld` logs the suppressed recovery and avoids additional `RefreshPolicyEx`, Dnscache `paramchange`, and DNS cache flush calls.
- Type: time duration string
- Required: no
- Default: 30m
## Upstream
The `[upstream]` section specifies the DNS upstream servers that `ctrld` will forward DNS requests to.
