FPP Proxy Settings not working for F48V4

[Wodrith]

Does anyone have FPP proxy settings working for F48V4?

I connect to my FPP over wifi. FPP v4.6.1 is running on a Raspberry Pi 3+. I utilize proxy settings to connect from eth0 of the Pi to a switch that has an F48 and an F48V4 on it. The proxy settings from the FPP work for the F48 and I have been using that for a few months. The proxy setting for the F48V4 I cant seem to figure out. When I go to the page that should work, I get a Error 404 page not found (different then the page you get when you dont have connection to the device).

My network is setup as such.
Router:
IP 192.168.1.1
Has a static route for:
Destination 192.168.100, gateway 192.168.1.115

The FPP instance:
eth0
IP: 192.168.100.2
netmask:255.255.255.0
Gateway: blank
DNS server 1: 192.168.1.1
DNS server 2: 8.8.8.8

wlan0:
ipaddress: 192.168.1.115

In the proxy window, I have configured 2 proxies:
192.168.1.103
192.168.1.106

on the F48:
IP: 192.168.100.3
Gateway: 192.168.1.2
mask:255.255.255
Primary DNS: 192.168.1.1
Secondary DNS 0.0.0.0

on the F48V4
IP: 192.168.100.6
Gateway: 192.168.100.2
mask:255.255.255.0
DNS 102.168.1.1

wlan: 192.168.1.78

I have found that FPP can see the the F48V4, as if you enter channel outputs and set an ip address, you will see information on the status page if it cant see a device. From the F48v4, they added a feature where you can ping IP addresses, and I can ping the gateway (the FPP). If I run a sequence, I can sent data to the F48V4 as I can see packets on the information screen change. So everything works, BUT trying to connect over ther FPP as a proxy, IE
http://192.168.1.115/proxy/192.168.100.6/ doesnt work for F48V4
http://192.168.1.115/proxy/192.168.100.3/ does work for my other controller

There have been a few firmware changes that addresses some bugs in the F48V4. Jump in the Zoom room, there are several people in there that have the most recent firmware.

Shouldn't the proxy window contain the IP addresses of the Falcons?  so in your case 192.168.100.3 and 192.168.100.6 ?   What are these two addresses as I don't see them referenced in what you described.

I'm fairly certain you need to be using FPP 5.1 for the proxy things to work with the Falcon v4's.

FPP 5.1+ and F48v4 Build 5+ is the working combination, versions before them have challenges with the proxy.
