There are a few things to try and solve this issue. First, make sure that your Microsoft account has a Gamertag by logging in to or the Xbox app. Then, I would recommend reinstalling the game on your PS4 system. That should force the game to make you login again. On a different device, open your web browser and navigate to the URL displayed in Minecraft. Enter the code displayed in Minecraft and click Next. Enter the email address, phone number, or Skype username for your Microsoft account and click Next. for more details review my website remoteconnect ps4 minecraft
