Kodi nfs problem

I hope someone can help?

Everything was working great, i decided to update from 16.1 to 17.1 and now when I go to click on nfs for kodi to find my synology drive the wheel on the screen spins then stops? It doesn’t even open the next page to show drives on network? I even went back to 16.1 and get the same problem? Tried it on my laptop on 16.1 works fine. As I say it has all worked fine so all the settings show be correct.
