Plants Versus Zombies GW2 Online Connection Issues

I've had PVZ a little while now and when i first got the game i was able to play the game flawlessly. I had no issues with online or anything. However recently I've tried to play with my friends at it would crash a minute later. Then i tried to play online by myself and again the game would crash within a minute. So I'm not sure if its a problem with the servers or my internet. I'm just not sure, if anyone could help find a solution that would be great.
