Brand new install of version 2.9.14 License Level 5
Ran the Hotspot Setup
But at the end it says my hotspot server is invalid with no clue in the logs as to why.
I need to put three of these in place in the near future.
Please help. 
One idea you could check:
Do you actually have an ip address from the DHCP pool address range on the hotspot interface? So if your DHCP range ist 10.0.5.0/24 and you want to run HotSpot on wlan1, do have an address starting with 10.0.5. on interface wlan1?
Best regards,

The IP address of Interface Hotspot is 10.5.50.1/24
hs-pool-2 is 10.5.50.2-10.5.50.254
Yes…
Does Hotspot only work with wireless interfaces?
Do you have the DHCP package installed?
