Same here, I bought my PS4 in mid January and everything was working fine. After the 1.61 update, whenever I try to access the PS store I am given an error message with no code. The same thing happens when I try to access Netflix or any other TV & Video service. Verified the internet connection and it was fine, so I decided to initialize the PS4 hoping it would fix the issue, but it did not work. The strange thing is that its able to log on to the network, and just this morning it downloaded an update for play room(since I initialized it). For now I will just remain patient and hope they come up with a fix soon.
