You need to tell the local clients to renew their lease manually.

For Windows:
ipconfig /release
ipconfig /renew

But you need to do some research and use AI. Its great for these kinds of things.

Is that a typo in the dhcp server address, which is different to the address assigned to the client?

Instead of making us guess, can you please tell the setup, what is the OPN version, which dhcp service are you using on it, what are the devices involved in the setup? Perhaps a router behind another router. Maybe more than one dhcp server running on the network.
