I have been changing my opnsense config to use pihole and all is working.
I rebooted the opnsense and was looking around the logs and configs.
I noticed this in the unbound log:
2021-08-10T21:25:43 unbound[81973] [81973:0] info: generate keytag query _ta-4f66. NULL IN
2021-08-10T21:25:43 unbound[81973] [81973:3] info: generate keytag query _ta-4f66. NULL IN

2021-08-10T18:39:53 unbound[81973] [81973:0] info: generate keytag query _ta-4f66. NULL IN
2021-08-10T17:42:32 unbound[81973] [81973:0] info: generate keytag query _ta-4f66. NULL IN
2021-08-10T17:16:22 unbound[81973] [81973:2] info: generate keytag query _ta-4f66. NULL IN
2021-08-10T17:16:21 unbound[81973] [81973:0] info: start of service (unbound 1.13.1).
What is this? Is this a normal thing (I never really looked in the log of unbound)
Or is it something I have done incorrectly or missed? Somebody else experiencing this?
One of the more experienced members will probably know what this Null IN means and if it is a fault of config or an non harmful message.
thank you for your help and explanation in advance!
still seeing similar mentions: unbound[47709] [47709:1] info: generate keytag query _ta-4f66. NULL IN
Who can explain what this [generate keytag query _ta-4f66. NULL IN] means?
Seen the same log entries on my OPNsense system;
Some how Unbound stopped (RED) and this is in the log when starting at 2021-09-17T06:18:49 from the Dashboard;

I started using dns over TLS when this happened:
