Borderlands 2 for all that is holy please help me!

So I just started playing borderlands 2 on ps4 my brother told me about shift codes and so I wanted to check it out so go to extras go to shift code and click on it did that and it says you must agree too blah blah blah so go ok and poof everytime it says unable to communicate with gearbox software shift please try again later I have tried everything and still cant figure it out please help or am I just wasting my time.

I’ve found it easier to do everything through the website.

When you go to the site click on SHIFT in the top Menu. Create an account if you haven’t done so already. It will have you link your PSN to the SHIFT account. I actually redeem all my shift codes from the web site as well, it’s just far less cumbersome.

You probably (judging by the date of your post) caught the SHIFT maintenance window. If it still isn’t working for you, post again/
