Happy new year everyone! 
After a failure in accessing .co.il domains with unbound 1.9.0, I decided to give it a go and compile unbound 1.13.0 on my RaspberryOS (Debian Buster).
I’m encountering issues that I’m out of ideas on how to solve.
- Cannot open log file (despite it’s configured in unbound.conf)
- Cannot use the unbound-checkconf utility
I provided a link to my config file at the bottom.
Appreciate your help!
