FaceTime, Game Center, Messages: Troubleshooting sign in issues
In rare situations, when you try to sign in to FaceTime, Game Center, or Messages with your Apple ID you may receive one of the following alerts:
- "Could not sign in. Please check your network connection and try again"
- "Could not sign into Messages. Please check network settings and try again"
- "There was an error processing registration"
- "The requested operation could not be completed due to an error communicating with the server"
Try the following:
- Ensure that you have an active Internet connection.
- Verify that you are using a valid Apple ID at appleid.apple.com. You can also create an Apple ID or reset your password from this website. Other things you should confirm while logged into appleid.apple.com:
- Confirm that the email addresse(s) for your Apple ID has been verified.
- Check for miss-types of the email address
- Check the spelling of the email address
- Check that all letters are lower case
- Make sure that special characters are correct, e.g. no commas (,) where there is supposed to be full stops (.), etc.
Note You may experience issues if your email address is associated with more than one Apple ID. If you have multiple Apple IDs, log in to appleid.apple.com with each Apple ID and confirm that each email address you wish to use for FaceTime or Messages is associated with only a single Apple ID.
- Make sure the date, time, and time zone are set correctly in Data & Time preferences, in System Preferences. Tip: Enable "Set date and time automatically" in Date & Time preferences to automatically keep this information accurate.
- If third-party firewall or port filtering software is installed, it needs to be configured to allow connections to apple.com and verisign.com. A list of ports required for using FaceTime and Messages is in Using FaceTime and iMessage behind a firewall. Please consult this article for further help configuring firewalls and Internet security software.
- If your /private/etc/hosts file has been modified, make sure that it is not interfering with communications to apple.com or verisign.com servers. Note: Some third-party software installers may modify the /private/etc/hosts file without alerting you. Instructions about how to check and resolve issues with a /private/etc/hosts file are in the "Blocked by configuration: (Mac OS X/Windows)" section of iTunes: Advanced iTunes Store troubleshooting.
