I use Retrofit library to send request to server's API. My server Url is on HTTPS protocol. Sometimes I get this error while after some minutes i restart app and it fixed.
SSL handshake aborted: ssl=0x55ad47e080: I/O error during system call, Connection reset by peer
I read all answers in stackoverflow and set TLSSocketFactory.java but the problem not solved.

Why this error occurred and How can I solve it?
