We run configless. If we add a node to slurm.conf and don't restart slurmd on our submit nodes, then attempts to submit to that new node will get the error you saw. Restarting slurmd on the submit node fixes it. This is the documented behavior (adding nodes needs slurmd restarted everywhere). Could this be what you're seeing (as opposed to /etc/hosts vs DNS)?
Links to the official Slurm documentation and presentations about adding/removing nodes can be found in the Wiki page https://wiki.fysik.dtu.dk/niflheim/SLURM#add-and-remove-nodes
