Laravel 5.2로 Mysql 서버에 연결할 수 없습니다.

내 laravel 설치에 MySQL 연결을 추가하면 작동하지 않는 것 같습니다. 원격 서버에서도 모든 설정을 두 번 확인했습니다. 자격 증명이 정확하고 모든 것이 작동합니다. 아래에 내 컨트롤러,보기 및 database.config 파일을 게시하여 무엇이 잘못되었는지 확인할 수 있습니다. 나는 지난 2 시간 동안 이것을 고치려고 노력해 왔으며 무엇이 잘못되었는지 전혀 모릅니다. (데이터가 있는지 테스트 할 때 테이블이 존재하지 않는다고 말하지 않으면 null을 반환합니다. 권한 선택)
