Gallery and music lost link with SD card

Hi. I can read SD card content, photos and everything's been written there, but if I try to open something from any app it only shows internal memory contents. It's like SD card was not there. If I open music app, it doesn't show anything either, scan show no results.
If I go to file manager I can see SD card and everything, but not from gallery or music app

Any ideas on what happened here and how can I fix it?
