Can't access WUI of switch on green network

While using the proxy server, I cannot access my Switch’s WUI when I’m connected to the IPFire proxy on my machine, it just says access denied. My machine and the switch are both on the green subnet and I can only access the WUI when I take off the proxy settings on my desktop. This just started doing this recently and idk what I could’ve changed for this to start. transparent mode is disabled I only have the proxy enabled.
