git - ssh git kex_exchange_identification：读取：连接由对等方重置

问题描述

几天前一切正常。现在给我同样的ssh -T git@gitlab.com输出。ssh -T git@github.comkex_exchange_identification: read: Connection reset by peer

我在互联网上尝试了一些建议，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

解决方案

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

我发现我的 /etc/ssh/ssh_config 文件中的端口被意外更改了。
一旦我将端口改/etc/ssh/ssh_config回 22，我就可以连接到 Gitlab。

尝试ssh -Tv git@gitlab.com看到更多。

OP Fazar在评论中确认从 git 2.25 升级到 2.33 足以解决问题。
