The problem is not with your watch or your ANTstick, the problem is with GarminConnect's servers!
You can wait for Garmin to fixes the problem, or you can use "manual upload" (the button at the top right corner of your GC page) to send the data from your computer to yur GC account. If you've never done a manual upload, check out this thread --> https://forums.garmin.com/showthread.php?32850-Garmin-Connect-failed-due-to-server-error
Same thing: "Activity transfer to Garmin Connect failed due to server error." I see the uploaded file in my activities folder, and can upload it to training peaks, but it does not show up on the dashboard.
Got the same problem "Activity transfer failed due to Server error". Tried to manually upload the 2 last activities, without success so far. Help please. Additional infos: GC doesnt seem to be able to read the activities data from ANT Agent (version 2.3.3 on Win 7 Enterprise 32), while Runkeeper saw the activities. Forerunner 610 version 2.80
Same problem for my, only with my FR610, not with my Edge 500. I can see the activities when I try to do a manual upload, but it fails to upload any of them. My activities all show up in Training Centre and SportTracks.
