[squid-users] Windows 10 Feature Updates not coming through

Hello.  I can't figure out why, but I can get regular windows 10 updates
through the proxy without problem, but the larger feature updates (1803)
always fail to download.  I can do the windows 10 update assistant
manually, and that seems to work ok.  I'm not sure what I am missing.  Do I
have a problem with my configuration?  I am trying to do the download
through port 4120.
