Captive portal not prompting

Question

Hi, im using captive portal, but sometimes it doenst prompt, so i have to enter the ip of the firewall to log in manually (192.168.110.3:8090) so i want to know if there is a way to set a name instead of the ip, something like login.something (or at least something:8090) 
 
 thanks a lot.

I have had this with UTM as well, I get the user to restart their phone, and all is fine then, this has been usually after an update to the phone. Not sure why though.
