PlayStation sign in error - what to do?

I have not been able to log in to Psn for 2 days, because it always says: This function is temporary
not available, please try

it again later

(CE-41489-6). '

When I searched for this error code it turned out that it supposedly doesn't exist, what should I do now?

Which playstation?

PS4

Ok because I know myself well from these error codes will not help you either because these error codes are different for each ps4, look on your cell phone or pc if you still have access to your psn account, if so then restart your ps4 times it can work again but it can also be due to your internet.
