My activity can not be imported in gamin connect (CLOSED) garmin sync service was down

garmin watch 255 version: Version 12.25

I finished as usually a long run (1h45) and save it on my watch byselecting my strength and my feeling score.

But this activity was never synched on my phone, ( I retry several time)

I try also a windows garmin sync but this last activity was not synched too

I downloaded from by watch 'in USB' the ".fit" file corresponding to import in on garmin website.

But this activity failled also to be sync with this error :

Garmin can not load this activity BUT

I success to import this ".fit" file in Strava via webpage import.

thanks for the support.
