WAN DHCP client doesn't work properly after reboot but it used to

[network_pseudonym]

I have to manually renew the DHCP lease on the WAN connection after a reboot of the router, the WAN link will not work until I do so. This did not originally happen when I installed OPNsense earlier this year, but it has persisted through a few updates.

I don't remember the precise changes that I made or updates I applied when this started happening. I vaguely remember doing something with the interfaces but not exactly what it was, or if that was actually when it happened.

Is there anything that might cause this, or any setting I can use to force it to get a new DHCP lease periodically if there is no valid one existing?
