無法透過 ssh 連線到伺服器

Question

我跟著這教程，當我嘗試連接到伺服器時，出現此錯誤：

packet_write_wait: Connection to x.x.x.x port 22: Broken pipe

從sudo journalctl -u ssh.service我得到：

Aug 14 03:16:34 my_server sshd[2280]: Accepted publickey for myuser from my_ip port my_port ssh2: RSA *********
Aug 14 03:16:34 my_server sshd[2280]: pam_unix(sshd:session): session opened for user myuser by (uid=0)
Aug 14 03:16:35 my_server sshd[2280]: pam_unix(sshd:session): session closed for user myuser 

我在資料夾外部創建了用戶/var/www，並將我的電腦 shh 密鑰添加到authorized_keys伺服器上。
