Playstation 4 login problems?

I have login problems with my Playstation 4. For me, the message that I somehow logged in with 2 accounts popped up. I wanted to see what that might mean. Therefore, I'm on account management and have entered my E MAIL address and my password. That did not work that's why I changed my password and then it worked but now it appears:

What should I do now?

It says that you should try later, then you should do that too. XD

Would it try tomorrow, if it does not work, you should be worried, although I doubt it will not work!

OK

If it still does not work contact the support because you get good and quick help
