Finally it seemed to be fixed in the VyOS 1.5-rolling-202401090834 version I updated today to latest rolling and its fine now 👌

now this output is from a fresh install i made with latest rolling release do you see any difference in configurations/ permissions ?

Can you please paste the output of ls -ld /config/dhcp and ls -l /config/dhcp. It is possible you might have installed a version _before_ 1.5-rolling-202401030023 and the instance is carrying forward the misconfigured directory/file persmissions.

Yes I tested again upgrading with today's latest rolling release no ip address is served to clients so issue persists no changes

Complete config
Admin@vyos:~$ show dhcp server leases

Still issue persists when u create a new install its fine but upgrading breaks dhcp server ,tried in latest rolling releases 😢 why no solution??? YET...........

What I noticed is whenever you update rolling versions it breaks dhcp ,but when you make a new install it is fine.
Just to report back
