Work around to not being able to find games (Console).
Many people playing BF4 on console have been having the issue of not being able to find or join matches on their own (no servers appear in the browser, quick match plain doesn't work). If you are having these issues then you have to join off of a friend who can until DICE releases an update.
I can't verify if the same issue is on PC, or if this works for you whom are on PC, but this is the only workaround for console users. Note, the issue is gamertag specific. Tested by myself and three other people I know in person. We used multiple gamertags on the same systems (PSN as well) and on both PS3 and 360 the issue only had risen for certain gamertags/PSN ID's.
