How To Deal With PS4 WS-37397-9 Error

emailtemplatelogosI’ve noticed that one of the most recurring concerns in our local PlayStation community is about the dreaded WS-37397-9 error. Here you’ll learn more about the nature of the error as well as some tried and tested ways to deal with it.

What in the hell is the WS-37397-9 error?


The WS-37397-9 error is most commonly associated with IPs that Sony Entertainment Network(SEN) has banned. Due to numerous successful hacking attempts at their network, they automate the banning of IPs that shows suspicious activity.

Why am I getting this error?

Chances are, it isn’t your fault that your IP is banned from accessing SEN. Most ISP use Carrier Grade NAT types (CGNAT) a technique that allows them to crams dozens of users under one IP. All that user activity under one IP causes SEN to flag the address for banning.

How in the world do I fix it?

There has been no reported case of IP’s getting un-banned, but there are workarounds you can try that are easy enough to do. Bear in mind that these aren’t guaranteed to work; what has worked for others might not work for you.


Let’s start with restarting your modem. This will result in getting assigned a new IP, one that may or may not have already been banned by Sony. You can also try to manually switch your primary DNS to and your Secondary DNS to as this seemed to have work for some users. Other things you can try are to either forward the SEN ports or set your PS4’s IP to DMZ (look up how to do these online as it’s different for every router model). The most permanent possible fix I can recommend is to request a static IP address from your ISP; a usually paid-for priviledge.


Simply resetting your network settings or restarting your phone entirely could do the trick. If not, the best hope you’ve got is to toggle your network mode down to 3G only when accessing the PlayStation Network and toggling back up to 4G when you’re done. If any of these don’t work then your shit out of luck as there’s hardly anything else you can do at this point. You can’t ask for a static IP here, your mobile data just doesn’t work that way.

As I’ve mentioned, there is no guaranteed fix for this error, and it also seems to be different for everybody, but hopefully these general tips will work for most of you and at the very least, give the rest insight on the nature of this error. Hopefully, Sony finally addresses this issue and possibly make adjustments in their security measures to address it.
