Hi DanDy001,
I noticed that you mentioned no critical, error or warning regarding DHCP lease in event log, then are there other event information recorded?
If you have tried a lot and it still doesn't work, we may export DHCP configurations and reinstall the DHCP role, to check if it solve the issue.
We may use the following steps to export DHCP configurations and import the configurations after reinstalling the role:
step1:Dump the configuration file use command “netsh dhcp server scopeID dump >filename.txt ”
step2: Remove DHCP role and reinstall it.
step3: Import the configurations use command “netsh exec C :\filename.txt”
step4: Restart DHCP server
Best Regards,
Anne He

You didn't perform any migrations right?
Restarting service didn't change anything?

Nope. Tried restart Service and server. Same problem and there is no other DHCP server on the network.

have you had a play around in cmd/powershell using the NETSTAT command?
netstat displays current tcp/ip settings
netstat -a (to list all connections and listening ports
i am not sure if this will solve your issue but it should show you the IP addresses the router has assigned.. NMAP is a more indepth network scanning tool if u want to download that
