Garmin fenix 6 pro solar disconnects and connects

My Garmin Fenix 6 Solar has worked flowless since I bought it in December 2020. Now It has started to connect and disconnects from garmin connect then and now. It started some days ago. 

I have tried to restart the watch but the problems are still there. 

I have som more Garmin watches like Venu and instinct and I have not that problem with them. What can I test to do? Hard reset, does it reset the hole watch?
