Help with controler

why would a led controller work on 1 strip then stop but work on a different strip when both strips seem to work just not the original controller on the first strip? Everytime i use what i thought was a broken controler on a different strip it works. I try a different controler on the original strip and it works. So not the strip. What gives? I reconnect after both the strip is working and the original controler and the strip and controler no longer work. Its so odd. For some reason the original controler just doesnt like this strip anymore but plays with all the others lol nothing wrong with first strip confirmed .
