All things that require internet connection on my PS4 will, seemingly at random, stop working. This includes parties, games, and apps like YouTube and FunimationNow. I don't think it's actually losing connection because I can go into the network settings, test my connection, and it'll tell me almost immediately that the connection is great. I can then use all the things I mentioned before for sometimes seconds, before it happens again. Whenever I first get on my PlayStation it seems to work just fine for a while though. I tried Googling the issue, but it's really specific, and I just couldn't find any answers. I would really appreciate some help.
