My son rarely restarts his computer, so I just did it for him. Now when he starts up Steam and tries to connect to his Friends list we get a notification that https://steam-chat.com has been blocked, and he is unable to finish logging into the steam friend servers. Is there some reason a steam server would be blocked as a potential threat? I've added steam-chat.com to the approved list but am kind of worried as to why it would have been flagged in the first place.
