Webdav에서 401 관련 문제

안녕하세요.
포럼 질문이 모두 공개질의고 비공개가 안되는것 같아 질의에 제한이 있네요.
아래 로그의 일부와 상황에 대한 캡쳐를 보내드립니다.
(일부를 가립니다)



위와같이 드라이브를 제대로 읽어오지 못하면서
지속적으로 문제가 발생하며 원격 webdav 상태에서만 발생하는 문제입니다.
동상황 발생시 로컬 smb에서 문제 없음을 확인하였습니다.
(유료버전입니다)

아래 로그입니다.

안녕하세요, @rbpeople 님.

401 오류는 WebDAV Server가 반환해 주는 오류입니다.
SMB는 별도의 프로토콜이므로 별개의 문제입니다.

외부에서 접속 시 401 오류가 발생하면 내부에서도 WebDAV 테스트해 보실 것을 권장합니다.
내부에서 WebDAV 사용에 문제가 없다면 다음 사항을 확인해 보시기 바랍니다.

  1. 공유기(라우터)의 포트포워딩이 제대로 잘 되어 있는 지 (NAS에서는 라우터 설정을 하지 않도록 합니다.)
  2. 방화벽 또는 Reverse Proxy 설정이 있는 지 확인하고 문제가 없는 지 확인합니다.
  3. 공유기, WebDAV 설정에서 IP가 차단되어 있는 지 확인합니다.
  4. Password가 만료되어 있지 않은 지 확인합니다.

각 네트워크 단을 확인 후 결과를 알려주세요.
