I just went to play bf 4 on pc one day and this error came up saying port 3659 UDP isnt open. I never changed any settings to close this port so i have no clue how it happened. Ive tried port forwarding, restarts of all programs bf 4 associates with, reinstalls, updati g punkbuster. Nothing works. And as per the norm the ea answers page isnt helping either. Any have any ideas?

A temporary way to fix it is to shutdown your internet browser and origin client then relaunch both, worked for me atleast but only til i had left a game or 2

I tried opening the port up manually, but it said that the port was already in use or something like that, but even through i got the error message it still fixed it

i just found a fix. for some reason manually porting it forward wont work so i downloaded a program called Smart Port Forwarding. i entered in a new task for it to open up port 3659 in both UDP AND TCP. its been working fine for 24 hours.
