Forerunner 955 Solar: Activity not synchronized with Garmin Connect

Today my run activity has not been loaded to Garmin Connect Android app.

I tried to sync many times through the app and the watch.

I also tried to upload manually the fit file in Garmin Connect web app but it failed as well.

I uploaded successfully the same fit file in Strava.

So the fit file is probably not corrupted consequently I guess the upload/sync service is failing.

  • I also had this behavoiur once and there the file was corrupted. Connect is a diva in this case because all of the other online services had no problem. Most of the repair services dit not even encounter a problem with the file...

    But you can use this tool to repair it:

    If you need some advice in using it, just let me know. I can also offer you to repair the file since I have it already working there.

  • Thanks Stefan.

    I will try the Garmin fix tool.

  • Thanks Stefan, the tool worked well.

    I also contacted Garmin support (France).

    They recommended to synchronized the watch with Garmin Express.

    I did it.

    My last multi activity training session was loaded in Garmin Connect successfully.

  • I also face the same problem occasionally. I have noticed that this occurs only with running activities. The only way to load the activity to Connect is by syncing my watch via Garmin Express.

    I should have been more precise.

    I did not synchronize my activities via Garmin Express.

    It was a kind of one shot action.

    I guess it updated system files (?).

    My last activity was synchronized via Garmin Connect Android.

  • I didn't say that I use this method consistently to sync my activities. I just said that I resort to this method, when, rarely, Android Connect app refuses to do so.

  • I think this might be two different issues. It also happened to me once that the .fit file on the watch is somehow corrupted that garmin connect does not read it anymore (where other tools are much more tolerant there). It does not sync anymore this special activity also with garmin express.

    I have no idea what went wrong there, but the garmin tool fixed it for me... and also for
