Ps4 has connected with others?

I was just about to look at my Ps4 Twitch, but suddenly there was something about a missing license and that my Ps4 is now connected to others and is no longer the primary one? I don't know anything about it, but I only have a Ps4 and now I'm a little worried because my bank account is linked to my account.

Addendum: If I try to set mine as the primary one again, there's only an error due to network maintenance or something.

Can you send me a picture of this message
