Hello,

I can find two successful login attempts on our server:

[shfchen@linux ~]$ sudo cat /var/log/secure | grep 140.211.166.217
Oct  3 00:17:04 linux sshd[10238]: Accepted publickey for debi_adm from 140.211.166.217 port 56915 ssh2: RSA SHA256:VzG9tNbWoaaqqsjrW9e6NzlhgIcwz8ZlVkc76fR1q2Y
Oct  3 02:15:44 linux sshd[10241]: Received disconnect from 140.211.166.217 port 56915:11: disconnected by user
Oct  3 02:15:44 linux sshd[10241]: Disconnected from 140.211.166.217 port 56915
Oct  3 16:29:54 linux sshd[22419]: Accepted publickey for debi_adm from 140.211.166.217 port 42715 ssh2: RSA SHA256:VzG9tNbWoaaqqsjrW9e6NzlhgIcwz8ZlVkc76fR1q2Y

P.s. The log timestamp is UTC+8.

I have no idea why the push attempt would failed.
