My phone (Lg g2 mini) doesn´t read sd-card correctly, but the computer does

My phone suddenly told me that these applications i had on sd card isn´t installed. I knew that it means that my phone dose not read my sd-card, so I tried rebooting it. But it didn´t work. So I checked if my sd could have come out, but it wasn´t the problem. Then I tried if my sd card works on my computer and it did. Now I have searched for help, but have come back empty.

Could you please help me
