안드로이드(클라이언트)에서 소켓 생성시 예외발생하는 데 어디에서 문제가 생길 수 있는건가요 ?

서버는 자바로 만들었고, 클라이언트도 자바로 만들어서 실행시켰을 때 서버에서 문제는 없었습니다 .
서버가 잘되는지 확인하고 안드로이드를 실행시킨 것입니다.
서버도 포트번호를 5555로 열어두고 나서 안드로이드를 실행시켰습니다.
로그를 찍어보았는데 다음과 같이 나왔습니다.

이처럼 소켓이 생성되기 전인 로그 connect2가 찍히고 난 후, catch문으로 넘어가드라구요.
이러면 소켓을 생성하지 못하는 건가요 ?
어떤 이유에서 예외가 발생하는 것인지 궁금합니다.
아니면 제가 무엇을 생각하지 못했거나, 빠드렸을 수 있을까요 ?
도움 주시면 감사하겠습니다!!
