title: Using SSH over the HTTPS port
intro: 'Sometimes, firewalls refuse to allow SSH connections entirely. If using [HTTPS cloning with credential caching](/github/getting-started-with-github/caching-your-github-credentials-in-git) is not an option, you can attempt to clone using an SSH connection made over the HTTPS port. Most firewall rules should allow this, but proxy servers may interfere.'

{% tip %}
**{% data variables.product.prodname_ghe_server %} users**: Accessing {% data variables.product.prodname_ghe_server %} via SSH over the HTTPS port is currently not supported.
{% endtip %}
To test if SSH over the HTTPS port is possible, run this SSH command:
```shell
$ ssh -T -p 443 git@ssh.github.com
> Hi <em>username</em>! You've successfully authenticated, but GitHub does not
> provide shell access.
```
If that worked, great! If not, you may need to [follow our troubleshooting guide](/articles/error-permission-denied-publickey).
## Enabling SSH connections over HTTPS
If you are able to SSH into `git@ssh.{% data variables.command_line.backticks %}` over port 443, you can override your SSH settings to force any connection to {% data variables.product.product_location %} to run through that server and port.
To set this in your SSH configuration file, edit the file at `~/.ssh/config`, and add this section:
```
Host {% data variables.command_line.codeblock %}
Hostname ssh.{% data variables.command_line.codeblock %}
Port 443
User git
```
You can test that this works by connecting once more to {% data variables.product.product_location %}:
```shell
$ ssh -T git@{% data variables.command_line.codeblock %}
> Hi <em>username</em>! You've successfully authenticated, but GitHub does not
> provide shell access.
```
