nslookup github.com
;; communications error to 127.0.0.53#53: connection refused
;; communications error to 127.0.0.53#53: connection refused
;; communications error to 127.0.0.53#53: connection refused

exit

2025/12/08 18:41:33 failed to run bash: exit status 1
Error: running command "boundary": exit status 1
time=2025-12-08T18:41:33.869Z level=ERROR msg="Command execution failed" error="exit status 1"

This happens randomly.
