21.1 Legacy Series / Re: Unbound DNS Locking Up
« on: June 25, 2021, 02:17:20 am »
I'm getting `status: REFUSED` DNS responses at times from Unbound according to dig lookups, with dig complaining about recursion not being available. Restarting Unbound "fixed" it at the moment but don't have confidence this will stay that way.
To be clear, not using DoT or an external resolver, I'm letting Unbound perform recursion itself. Also don't see anything obvious in the logs.
Code: [Select]
% dig example.com
; <<>> DiG 9.10.6 <<>> example.com
