Sync error message in "Calories in/out" in Connect

Hi. 

My Garmin is synced with MyNetDiary and everything seems fine. MyNetDiary takes the data from Garmin with no issues. 

When going to Calories In/Out in the connect app I get the error message "Linking accounts failed". I don't know if this has anything to do with the sync to MyNetDiary, but I suspect it does. 

Does anyone have any idea on how to solve this problem
