Arduino Leonardo does not upload the code!

Cordial gretings,

Hello, good afternoon, I need your help, since a few days ago I can`t upload any arduino code in my arduino Leonardo, When I try up a code I get

"Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

avrdude: butterfly_recv(): programmer is not responding".

Sometime I can upload the arduino code after waiting a long time.

Details:
I used to the platform arduino 1.9.0 and arduino 1.7.5 with the librery "arcore".
I have tried with other cables and upload the code from arduino 1.8.8.
