Problem scanning Windows 10 assets

[d_salomone]

Hi folks, I'm new in this forum. I'm using the free version of LanSweeper. Have been using it for a while with no problems (about 60 assets on my network). But suddenly, two of them (Windows 10 PCs) started to give problems when scanned. There are no errors shown regarding the scanning process itself, the !Errors tab does not show up in the asset page, but not all the scanned values are updated and last seen date is not updated and last tried date is shown in red.
Looking at the service's errorlog.txt file, it show entries like the following for those two assets:
