could not establish connection to “hostname”

解决方案

Try to delete the fingerprint (a single line that corresponds to this particular connection - not the whole file) saved within the known_hosts file. If in Windows, this is placed at C:\Users\<your_user_name>\.ssh\known_host whereas for Linux that would be within /home/<your_user_name>/.ssh/known_hosts dir.

尝试删除 known_hosts 文件中保存的指纹（与此特定连接相对应的单行，而不是整个文件）。如果在 Windows 中，它位于 C:\Users<your_user_name>.ssh\known_host 中，而对于 Linux，则位于 /home/<your_user_name>/.ssh/known_hosts 目录中。
