無法從遠端伺服器連接 SSH

無法從遠端伺服器連接 SSH

我在從雲端伺服器連接 sFTP 和 SSH 時遇到問題。我正在使用代理進行連接並已允許 IP 位址。當我使用同一代理從本機伺服器連線時，連線成功。只有當我嘗試從 Heroku 伺服器（建置於 AWS 之上）進行連線時，才會出現問題。我的日誌伺服器似乎不是很有用。

這裡是雲端伺服器連線不成功關閉連線的地方（使用代理）

debug1: PAM: setting PAM_TTY to "ssh"
debug2: monitor_read: 100 used once, disabling now
debug3: mm_inform_authserv entering [preauth]
debug3: mm_request_send entering: type 4 [preauth]
debug2: input_userauth_request: try method none [preauth]
debug3: userauth_finish: failure partial=0 next methods="publickey" [preauth]
debug3: mm_request_receive entering
debug3: monitor_read: checking request 4
debug3: mm_answer_authserv: service=ssh-connection, style=, role=
debug2: monitor_read: 4 used once, disabling now
sshd[1496]: Connection closed by 11.111.11.108 [preauth]
debug1: do_cleanup [preauth]
debug3: PAM: sshpam_thread_cleanup entering [preauth]
debug1: monitor_read_log: child log fd closed
debug3: mm_request_receive entering
debug1: do_cleanup
debug1: PAM: cleanup
debug3: PAM: sshpam_thread_cleanup entering
debug1: Killing privsep child 1497
debug2: channel 0: rcvd adjust 49545

這是來自我的本地伺服器的成功連接，與不成功的關閉連接的同一點（使用相同的代理）

1: PAM: setting PAM_TTY to "ssh"
2: monitor_read: 100 used once, disabling now
3: mm_inform_authserv entering [preauth]
3: mm_request_send entering: type 4 [preauth]
2: input_userauth_request: try method none [preauth]
3: userauth_finish: failure partial=0 next methods="publickey" [preauth]
3: mm_request_receive entering
3: monitor_read: checking request 4
3: mm_answer_authserv: service=ssh-connection, style=, role=
2: monitor_read: 4 used once, disabling now
1: userauth-request for user dev service ssh-connection method publickey [preauth]
1: attempt 1 failures 0 [preauth]
2: input_userauth_request: try method publickey [preauth]
1: test whether pkalg/pkblob are acceptable [preauth]
3: mm_key_allowed entering [preauth]
3: mm_request_send entering: type 22 [preauth]
3: mm_key_allowed: waiting for MONITOR_ANS_KEYALLOWED [preauth]
3: mm_request_receive_expect entering: type 23 [preauth]
3: mm_request_receive entering [preauth]
3: mm_request_receive entering
3: monitor_read: checking request 22
3: mm_answer_keyallowed entering

這兩次連線嘗試都是相同的（相同的代理、相同的使用者、相同的金鑰）。我現在真的很茫然，有人知道我能做些什麼來解決這個問題嗎？

確保： 遠端電腦的 IP 位址正確。 SSH守護程式正在偵聽的連接埠未被防火牆封鎖或錯誤轉送。您的使用者名稱和密碼正確
