[Net] - SSL: error:1408F10B:SSL routines:ssl3_get_record:wrong version number (nginx TrobleShooting)

2023/10/13 11:35:30 [error] 8676#8676: *1212 SSL_do_handshake() failed (SSL: error:1408F10B:SSL routines:ssl3_get_record:wrong version number) while SSL handshaking to upstream, client: 172.16.3.18, server: jenkins.bitsns.site, request: "GET / HTTP/1.1", upstream: "https://127.0.0.1:8080/", host: "jenkins.bitsns.site"

• proxy_pass https://localhost:8080;
  https://(는) 잘못되었습니다. http://. 이어야 합니다. 대상 URL이 HTTPS이더라도 프록시 자체는 HTTPS가 아닌 HTTP로 액세스해야 합니다.

접속을 /usr/share/nginx/html/login로 하는 이유?

• nginx location을 location = / 이렇게 잡았기 떄문!
  == 정확히 / URI에 대한 요청만 처리!

그렇기에 = 제거 후 nginx restart!
