[slurm-users] "error: slurm_auth_get_host: Lookup failed: Unknown host" in slurmctld.log

I keep getting this logged on my Slurm control host: [2024-08-06T20:31:40.196] error: slurm_auth_get_host: Lookup failed: Unknown host

I don't see an identifiable pattern and I'm not sure how to troubleshoot. The jobs being submitted at or around that time seem fine and nobody's complained about their jobs not running, so I can't track down a bad or nonexistent DNS record.
