New Kodi 17 on RPi3 - thumbs are not found

Hi

I have an issue with loading thumbnails of movies to Kodi 17 which is freshly installed on RPi3.

My setup is as follows:
I have RPi2 which was upgraded to OSMC with Kodi 17. I purchased RPi3 and installed a fresh copy of OSMC with Kodi 17.
My movies and music libraries are on a NAS and this is where the MySQL is installed.

After starting the RPi3 I noticed that the thumbnails are not copied. I used NFS in order to connect to the NAS movies folder.

The log file shows the following errors:

On the RPi2, where only upgrade was done, the thumbnails are cached and presented properly.

Has anyone else ran into the same issues?

anyone?
