Squid proxy halting program installation

awsiemieniec

pfSense 2.3-RELEASE (amd64)
squid 0.4.16_2
squidGuard 1.14_2

My kids like to play a game called Roblox. It's a simple browser game with a local install component. When I have squidGuard (transparent) enabled the download of a *.zip file fails and the installation kicks an error and stops. The installer is trying to get a *.zip from:
http://setup.roblox.com/version-ea1ccffcfea48fc-content-terrain.zip (see attached image)

The squid access table (image attached) shows that the various *.zip files the installer is trying to get are not cached (TCP_MISS/200) so it's reaching out to an IP to get them 54.231.49.140. If I add the domain "setup.roblox.com" and the IP 54.231.49.140 to the box "Bypass Proxy for These Destination IPs" with the Transparent Settings area nothing happens - meaning it still fails.

Update: Looks like when I download files I am getting:
The request or reply is too large

thanks.

You have got to be kidding me…
Package | Proxy Server Traffic Management | Traffic Mgmt
"Maximum Download Size" was set to 2048
?!

Set to "0" and all is fine.
