Question: I am working on Ubuntu 11.10
Local branch of my git-repo is up to date

I then wrote following command in terminal: heroku create --stack cedar and it said:  

Notice: on Wed, 20 June, our default stack will change to Cedar. <http://bit.ly/Lh0rM5>

Creating radiant-wind-7413... done, stack is cedar  

<http://radiant-wind-7413.herokuapp.com/> | git@heroku.com:radiant-wind-7413.git  

Git remote heroku added

All fine till now, then I typed following in terminal:

```
git push heroku master

```

and the following error occured:
**ssh: connect to host heroku.com port 22: Connection timed out  

fatal: The remote end hung up unexpectedly**

Answer: 
Most probably some sort of firewall issue or your network admin has blocked outgoing port 22 in your network. 

You may use simple scrip to see your connection to Heroku by :

`$ ssh -vvv git@heroku.com`

If you seeing connect timed out then you may need to request your admin to unblock port 22. Alternatively may access Heroku via **tunneling** as per my answer in [Connecting to heroku using port 443](https://stackoverflow.com/questions/14877088/connecting-to-heroku-using-port-443/19536371#19536371)
I added the https url to the .git/config file in my project folder. I found the HTTPS URL in the project Settings on Heroku. I then added that URL to replace the SSH url inside the .git/config text file.
