when I first got a ps4 I immediately created a psn account and bought a couple of games on the store itself. Mortal Kombat XL, GTA V, Assassin's Creed IV, and Ratchet & Clank. These games are quite sizable and because my internet isn't too fast they took quite long to download, so the PSN store was definitely working fine for a couple of weeks (4-5 weeks at most). Then I started noticing a problem logging in at my house with these two screenshots.
I tried everything and nothing worked. Then when I was at my sisters house, I was able to access store.playstation.com through her internet connection. So I assumed psn was down for maintenance but when I got back home it wasn't still wasn't working on mine. I assumed my IP was banned for some reason but then when I tried to log into my account at my sister's house a few weeks after it was also now not working. After a few weeks on not being able to access psn I tried again just out of curiosity and to my surprise it worked. But only for a few days. It has been doing this for the past few months, not access for long periods and then access for like a few days and then it's down again.
Can someone please help? I'm here because Sony said it's my fault when I know I didn't do anything malicious.
