  1. i get this error when i try to download the latest patch of overwatch, i havent been able to play overwatch since december, and the weird thing is that my ps4 works fine, all the other games can update fine, there is no lag, or problem with the network in any other way, and when i try to download overwatch it goes fine until it just stops, then it says “preparing to download (24%)” nad the percent keeps going up until 99% then it goes down to 4% and then it just stops, and instead of downloading, the download bar goes empty and the total of the download only says ” – ” as if nothing is downloading, after a couple of minutes I get this error or other erros that says that I cannot connect to the sever in time or something along the lines of that. please help, I have more than 600 hours in overwatch and I really want to play, I am even thinking about buying it for pc so that I can play, thank you in advance for helping me.

    1. if it won’t hamper your online data try to uninstall over watch completely and download all the data agian . If not check that you got the necessary space. I will suggest that you should get at least 20-50 gb of free space.

  2. Been having this issue with downloading any game since December the download always gets about a GB or less away from finishing then gives me the error and the download wont finish. Didnt seem to have any issues up until when I installed the latest system patch. I’ve tried every fix I could find online other then initializing the system. Any thought as to what the issue could be? Possibly the ISP? I’ve also been working in a different region then where my account was set up. Possibly region locked?

  3. 1473 only works once and if I try to connect mobile hotspot I can’t log into gta5 my Wi-Fi is working perfectly on everything else just not on ps4

  4. None of the methods helped 🙁
    Last week I have this problem and tried sign in via my phone and using the mobile data and didn’t have problems at all. But as soon as I switch to wifi – couldn’t sign in! Then all of sudden it fixed itself somehow!
    Then yesterday my sons was trying to sign in without success! After restarting the router he did sign in without problems. Today 12th May again troubles with signing in! Restarted the router – nothing. Can’t even sign via my phone?!? What should i do? How shall I contact?
    There’s got to be a solution!

      1. None of this works. LAN and WiFi are both fine. Internet connection is fine on playstation. Can not log into PSN on the consol. Very frustrating and no help works. Sony/PlayStation just tell me to restart machine and check my router settings. This is painful.

  5. Please help me, i have tried every method and nothing works, the WiFi works perfectly on everything else in my house but not my ps4 pro. Every time i try to connect to the internet it always fails, i have had this problem for like almost a month now. please help me!

  6. So im getting this code when trying to download a game. It downloads to 2% then gives me this code every time. None of these solutions have worked for me.

  7. My lan cable connection stopped qorking yesterday but my wifi works great.. Tried changing cable reboot modem.. Etc.. No luck..
