Unfortunately we found it isn't at the quality standard required to move forward

Hi, I get this review message about my item “unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.”

I want to know what is my problem and why it doesn’t have the quality standard required?
Can I fix problems and re-submit it?
