PS4 GTA5 Online has stopped working. What can I do?

Hi! GTA5 Online has not worked for about a week. Each time appears:

" WATCH OUT

Can't connect to Rockstar game service. Please check your network connection. Under http://www.rockstargames.com/support you will find information about failures and maintenance plans. Please return to Grand Theft Auto V. "

what can I do?

Just a counter question to clarify:

Do you have the PS Plus up to date?

Can you join other online games / services, or does an error message appear?

Hi! Yes PS Plus is up to date.
Other online games such as Fortnite work

The same for me, although I have a stable connection.
