DHCP not working on vpn100

SNTL

hi
I have a remote site where using vpn100 and the remote site is connected to the main site via a VPN tunnel. tunnel works fine but the remote side vpn100 is not assigning auto IP to devices and I have to add manual IP then the clients work. I have updated the latest firmware also on the remote site VPN 100 is still DHCP not working.
I just got the error as per the attached picture but it never shows up again.
the settings were never changed so not able to find the cause of not assigning auto dhcp.

seems some port forwording was causing this issue and after deleting that dhcp started to work.
