Resolving Error code: 85FB4400
When you try and refresh the Facebook integration or attempt to open a contact’s photos, you may receive the following error message:
Facebook error Not updated We're having a problem connecting. Try again later. Error code: 85FB4400
This problem is known as a “request level error", and is caused by a profile picture of any of your Facebook-synced contacts (or other Facebook picture that you attempt to open) failing to sync correctly with the People Hub. In most cases, the image has been removed; the owner may have deleted it from their library or selection of profile images, resulting in you being unable to view the profile or image without the error occurring.
Switching to another profile and then back to the one which caused the error message is a good way around this problem, as it refreshes the Facebook integration. Another workaround is to press Start > People > What’s New or Start > People > Contacts and check everything is syncing correctly. You can also tap and hold anywhere in the upper third of the People Hub and tap Refresh.
Note: While this is a persistent error message, it should not affect the rest of the Facebook integration on your phone. Check to confirm your what's new feed (tap people on the Start screen) and contacts are syncing (tap people on the Start screen and flick left). If everything is working, ignore the error message.
