ssh git kex_exchange_identification: 读取：对等方重置连接

Question

几天前一切正常。现在 ssh -T git@gitlab.com 和 ssh -T git@github.com 给我相同的输出 kex_exchange_identification: read: Connection reset by peer.

我尝试了互联网上的一些建议，但没有成功。我正在使用 Ubuntu 20.04 和 git 版本 2.25.1

ssh -Tv git@gitlab.com 给出这个输出

Answer 1

检查您的 ssh 配置，如 gitlab-org/gitlab issue 121570

I found out that the port in my /etc/ssh/ssh_config file was accidentally changed.
Once I changed the port in /etc/ssh/ssh_config back to 22, I was able to connect to Gitlab.

尝试 ssh -Tv git@gitlab.com 查看更多。

OP Fazar confirms in 从 git 2.25 升级到 2.33 足以解决问题。
