On screen: There was a problem connecting to the server.
When you see this one, the problem is most often on the operator's side and there is nothing on your machine to fix. Check the live status first.
Sony's explanation is the same as the on-screen line: there was a problem connecting to the server. Their first remedy is to check server status, which places the expectation on their side.
Worth settling the number first. The correct code is NP-34957-8. We checked Sony's index and NP-34957-9 returns a genuine 404 — it is not a code. The likely source of the confusion is that NP-34958-9 does exist as a separate real code, and the digits get transposed when pages are rewritten from each other.
Check the live status above first, as Sony instructs. If PSN is healthy, work down the list — these are all connection steps and they escalate sensibly.
Operator documentation: www.playstation.com. PS4 code only. And a note on sourcing: NP-34957-9 is not in Sony's index at all. If you landed here from a page about that code, the page was written about a number that does not exist.
