git - 为什么我在 git 上得到 ssh_exchange_identification : Connection closed by remote host?

Question

从终端克隆一个 repo:

git clone git@github.foohost.com:barrepo.git
Cloning into 'foorepo'...
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我已按照 generating and adding the SSH key 上的步骤操作但当 I test my SSH connection我有相同的结果:

ssh -T git@github.foohost.com:
ssh_exchange_identification: Connection closed by remote host

使用冗长的

ssh -v git@github.foohost.com
OpenSSH_7.9p1, LibreSSL 2.7.3

debug1: Local version string SSH-2.0-OpenSSH_7.9
ssh_exchange_identification: Connection closed by remote host

我可以使用 https 克隆存储库，但之后我无法执行其他操作( checkout/推送...)。

任何可能导致此问题或如何解决的建议？

在我的例子中，这是由于缺少 VPN 连接。
