Error Modifying WLC interface DHCP information

[abelriveron]

I'm trying to modify an existing DHCP servers configuration on a wireless interface in a Cisco WLC, however, once I Apply the change the below message prompts: "Error: Invalid IP address. The IP address entered is a Broadcast IP address".
Obviously there is no such broadcast IP address. Even if I want to make any change on that same interface such is Disabling the DHCP Proxy Mode, every time I Apply the change the same error prompts.
Does anybody has experience any similar issue?

Cisco WLC Software Version: 8.5.151.0

An screenshot is attached.

is it happening only on this interface ? Did u try to make one more test interface to with DHCP server address ?

Thanks for your reply. This is the only interface I have tried. I'm working on a production device so I cannot touch any other interface config.

You can create a new interface with a new wlan even in prod without impact. What the other have mentioned is to try with another interface to see if it’s the issue. Have you tried to change this from the cli?

Just curious, but could you list all the configured IP addresses of that interface?
