Minecraft PS4 account error

i trying link Minecraft ps4 to my mircosoft account has got error please fix problem

Hi i would like to ask why when i try to sign into my ps4 microsoft minecraft account it says there is an error to login

Si e verificato un errore durante la connessione al tuo account microsoft

[Edit - Translation] - PROBLEMS WITH ACCESS TO MICROSOFT ACCOUNT ON MINECRAFT PS4

non riesco a collegare account Microsoft e minecraft ps4 ogni volta che ci provo mi esce "si è verificato un errore durante la connessione al tuo account microsoft" ho gia provato sia a spegnere e riaccendere ma non funziona

[Translation-I can't connect Microsoft account and minecraft ps4 every time I try it out i get out "There was an error while connecting to your microsoft account" I've already tried both to turn it off and on again but it doesn't work]

As i said to someone else If you go on your PS4 MC then got to settings, profile, then while logged into the microsoft account you dont want, go down to Unlink Microsoft Account. It sadly doesnt work for me
and says maybe check internet connection. Tell me if it say the same for you

Yes, I get the same error message (check your internet settings) when I try to unlink my sons minecraft account that is connected to his PS4. By accident, I linked MY microsoft account to his (PS4) minecraft account. Is there a way to reset this? Please!
I really want to play minecraft with my son!
