coding.net 的 ssh 问题

coding 的 ssh 密钥用的之前 github 生成的，但是执行$ ssh -T [email protected] 时出现 ssh: connect to host coding.net port 22: Connection refused 的错误。
hexo 部署的时候会报

Please make sure you have the correct access rights and the repository exists. FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html Error: ssh: connect to host git.coding.net port 22: Connection timed out fatal: Could not read from remote repository.

的错误，这个该怎么解决？哪里配置错了吗？
