Under certain situations, users may encounter a failure to connect their Garmin account in the marketplace. This includes the following circumstances:
The Garmin account was previously connected to a Validic User which has since been deleted. A newly provisioned Validic User is now having issues connecting Garmin in the marketplace.
The Garmin account is still connected to another Validic User when another Validic User is trying to connect the same Garmin account.
In these situations, the user may either fail to retrieve Garmin data, or experience having Garmin disconnected from the marketplace automatically. This is due to a Garmin requirement where the Garmin account must first be de-registered in the Garmin API before the same account can be successfully authorized again through Validic.
Normally, the de-registration happens when the user manually disconnects Garmin in the marketplace. However, due to the situations above, it may not be possible for the user to manually unsync Garmin. To resolve this, the user may login to Garmin's website and remove the Garmin authorization from there:
Go to https://connect.garmin.com and login
Click on the user avatar
Click "View Profile"
Click "Edit Profile"
Click "Account Information"
Scroll to the bottom of the page. Under "Applications", click "Remove Permission" for the corresponding application.
Once done, the user should then be able to connect the Garmin account again in the marketplace successfully.
