Logos wont load after change link

I had working logos on my KODI on raspberry pi2. Then link for logos changed and it does not load logos anymore.On other devices logos working with same link like on windows kodi.
I double checked logo link and its correct. I did reinstalled simple IPTV client but same result.
Where can i find some cache for iptv logos in kodi? can it be cached or something?
any help guys?
thanks!
