I've recently returned to BF4 because of a new graphics card. The most glaring issues seem to be fixed. But I still get the "Game Error: Cannot connect to server" a lot in Battlelog. I'm confident it's not my firewall or router that's causing this. Is this something DICE still has to fix or is there something I can do on my end?

Also, the mortar is hilarious on some Rush maps. It incites flame like nothing else and with a little practice you can get a lot of kills.
