jsp에서 post방식으로 버튼을 눌렀을 때에 /pay로 리턴이 되면서 404 에러발생합니다. console에서는 org.springframework.web.client.HttpClientErrorException: 401 Unauthorized 에러가 나네요…

안녕하세요. 카카오페이입니다.
응답받은 에러내용을 모두 올려주시기 바랍니다.
올려주신 파라미터정보로 로그를 검색해보니 ready 응답이 정상제공되고있는것으로 확인됩니다.
현재도 이슈가 있는것인지요?

현재 콘솔창에서 나타나는 에러입니다
화면상으로는 404에러가 발생하고 있구요…

안녕하세요. 카카오페이입니다.
확인결과 귀하 계정내에 허용서버 IP주소가 설정되어, 해당 IP에 대해서만 호출이 가능하도록 설정된것입니다.
내애플리케이션 > 앱선택 > 설정 > 고급 > 허용서버 IP주소 에 해당값 삭제.

감사합니다! 그 에러는 해결되었으나 400에러가 발생하여 해결중입니다.
