Errore during synchronization between Garmin Express and Forerunner 405

7241143
3 months ago

Hi,

I have a Forerunner 405, which I paired successfully with Garmin Express (latest version).

I was able to sync my activities with Garmin Express, and to explore them in Garmin Connect.

But I can not sync trainings I have created in Garmin Connect : Garmin Express detect these trainings ("elements are ready to be installed"), but when I click on the "Install all" button, the sync starts, and a few seconds later, I always get this error  "There was an error during synchronization with Garmin Connect"

There is no more explanation about what causes this error, and I do not know where I could find detailed logs to get more information. I read on this thread it is possible to get logs, could you tell me where I can find them ? https://forums.garmin.com/apps-software/mac-windows-software/f/garmin-express-windows/101111/error-during-synchronization-with-garmin-connect

I also read this article https://support.garmin.com/en-US/?faq=2f0vGJzcfw25YTQEkzT1I7&productID=11039&tab=software , and did everything suggested :

- connect ANT stick to different USB ports (no hub)

- placed the 405 next to the USB stick, within 10 centimeters

- deleted all activities/trainings on my Forerunner 405, memory is free

- kept the device out of power save mode

- checked everything on Garmin Express : last version OK, Forerunner 405 serial OK, upload preferences OK

But the training sync from Garmin Express to my Forerunner 405 does not work at all.

I also tried to sync only one simple training with only one step, but same error...

Is there a way to get some logs to understand what cause this error ? Or better, a way to make the sync work all the time ?

Thanks.

    Another information : I deleted all the trainings which were ready to install in Garmin Express. The sync error remains, between Garmin Express and Garmin Connect.

    They may not be useful to your purpose but there are logs at C:\ProgramData\Garmin\Logs\Express

    Thanks @JohnfromPA

    I found the logs.

    I thought the problem was with my traning names, so I changed them and tried names like 20240816, but the error remains...

    It looks like there is an issue while downloading the tcx training file from Connect to my local disk :

    I have checked the path : C:\ProgramData\Garmin\CoreService\Devices\3524790538\Sync\Download\FitnessWorkouts\0kk2og2n.cjd

    The folders Download\FitnessWorkouts did not exist on my mcahine. I had only this existing path : C:\ProgramData\Garmin\CoreService\Devices\3524790538\Sync

    I tried to create the path manually : C:\ProgramData\Garmin\CoreService\Devices\3524790538\Sync\Download\FitnessWorkouts

    But it did not work either...

    I have detailed logs if necessary, but I can not write them down here, or my message is considered as spam...

    Any help from the Garmin tech team would be appreciated.

    Thanks.
