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.
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?
yeah it can be because of your ip. Try using vpn or possibly contact you isp for a ip switch
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
I started having this error after I downloaded 6.51 software and it hasn’t been working since.
1473 works fine after changing your mtu restart ur ps4
i get this error when i try to upload a video longer than 15m
may be storage error or your network cuts during the upload
My phone died using my mobile hotspot and never been able to connect again
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!
have you tried to contact with sony or you isp?
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.
Can you log in via PC or not maybe your ip got blocked
