Plex Media Server Local Networks Defintions

My local network is segmented into 4 different segments:
192.168.100.0/24 - Windows Server Network
192.168.101.0/24 - Client device network (Windows laptop, chrome book, Household owner phones)
192.168.110.0/24 - Guest WiFi
192.168.109/24 - VPN Network

All these network segments are running though my Sophos Firewall and Layer 2 Switch using VLANS (Plex Server has a single NIC)

I have set the settings in the Plex Server to the following:
List of IP addresses and networks that are allowed without auth
192.168.101.0/255.255.255.0, 192.168.110.0/255.255.255.0, 192.168.109/255.255.255.0

I am getting this error in the Console for each allowed network segments:
Error parsing allowedNetworks '192.168.101.0/255.255.255.0': An invalid argument was supplied
I have tried each of these network definition formats:
192.168.101.0/255.255.255.0, 192.168.110.0/255.255.255.0, 192.168.109/255.255.255.0
192.168.101.0\255.255.255.0, 192.168.110.0\255.255.255.0, 192.168.109\255.255.255.0
192.168.101.0/24, 192.168.110.0/24, 192.168.109/24
192.168.101.0\24, 192.168.110.0\24, 192.168.109\24

Any suggestions here?

Remove the spaces after the commas. :wink:

For better readability, use the abbreviated form of notating the subnet mask. x.x.x.x/24
