Recording error

Hi everyone,
last week I went skiing and used the ski mode. It worked fine on the watch but after i wasn't able to download any data to connect. I told myself that it was meant that way so i modified the OTHER activity but the same problem occur: record on the watch but doesn't upload any data to connect. usually i go running and it works fine so i tested it and the same problem occur. Looking into history I can only see the details of the activities of one week ago. Is there some settings preventing the correct recording?
PS both the watch and the app are up to date

Thank you in advance
