I added an entry to hosts for the download.httpproxy.fw-notify.net, and everything works in transparent mode now. I do get an error though, if once the content scanning has finished, you let it sit for a moment after clicking save, you will get this:
Could someone explain me the need of this "fw-notify.net" Domain.
What kind of job will "status.fw-notify.net" and "download.httpproxy.fw-notify.net" do for me?
