There was an error syncing with Garmin Connect

Thank you,

I have already tested other browsers with similar problems. Are you able to paste the content from this link:

Follow the instructions in this FAQ to delete corrupt data from the computer's hard drive: How do I remove FIT files that fail to sync in Garmin Express from my computer?

as well?

JanEri,

Have you tried resetting the browsers? Please find the article below:

Garmin Express stores activity files in a folder on the computer before uploading them to Garmin Connect. After a successful upload, the files are deleted from this folder. If a file contains data that Garmin Connect cannot import, the activity will fail to appear in the account and the file may remain in the folder.

Files that will not upload automatically should be manually deleted to ensure Garmin Express successfully syncs future activities.

To delete these files from the computer:

Windows:

Press the Windows key + R
Type %ProgramData% in the box
Click OK
Open the Garmin folder
Open the CoreService folder
Open the Devices folder
Open the folder with the 10 digit Unit ID for your device (this can be found on the About screen on the device if there are multiple folders present)
Right-click the Sync folder
Click Delete
Mac OS X:

Open Finder
Click Go from the menu bar
Hold down the Option key on the keyboard
Click Library, then release the Option key
Open the Application Support folder
Open the Garmin folder
Open the Express folder
Open the RegisteredDevices folder
Open the folder with the 10 digit Unit ID for your device (this can be found on the About screen on the device if there are multiple folders present)
Drag the PendingSyncUploads folder to the Trash
Empty the Trash
Once this folder has been deleted, future activities can now be synced in Garmin Express.

Thanks a lot!

Deleting the %ProgramData%\Garmin\CoreService\Devices\10 digit Unit ID\Sync folder seemed to fix my problem
