Hi,
As suggested,
8><--- Stop their services, start them manually one by one (ctld first), then watch whether they talk to each other, and if they don't, learn what stops them from doing so - then iterate editing the config, "scontrol reconfig", lather, rinse, repeat. 8><---
Error logs,
On node3,

I have checked the time, this is fine
munge.key I ran md5sum over it and get the same output.
When I reboot the warewulf nodes its a common Container file so 1~2 working but not 3 is just wierd.
On the controller,

So the controller is RHEL9 and the nodes Rocky8
However 1~2 and 4~7 work OK.
When I run,

I get a reason, its like the node is held down / off, does this need to be / can this be cleared?
