ssh git clone times out

Please help

I'm attempting to communicate with git / github on a linux ubuntu server via SSH while also having a different port for SSH ( not 22 ). When I attempt to git clone, I am using this command:

$ git clone -v [[email protected]:12345]:username/project-web.git myfolder

It hangs for about 3 minutes then I get this output:

Cloning into 'myfolder'...
ssh: connect to host github.com port 12345: Connection timed out
fatal: Could not read from remote repository.

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

I have my firewall ( UFW ) setup correctly; I can successfully SSH and connect to the server. This is my UFW configuration:

22                         DENY        Anywhere
12345/tcp                  ALLOW       Anywhere
12345                      ALLOW       Anywhere
22/tcp                     DENY        Anywhere
22 (v6)                    DENY        Anywhere (v6)
12345/tcp (v6)             ALLOW       Anywhere (v6)
12345 (v6)                 ALLOW       Anywhere (v6)
22/tcp (v6)                DENY        Anywhere (v6)

And this is my ~/.ssh/config file:

Host github.com
    User git
    Hostname github.com
    IdentityFile ~/.ssh/deploy
    IdentitiesOnly yes
    Port 12345

and my /etc/ssh/sshd_config file:

...
Port 12345
...

I've tried these other related SO answers and still no luck:

git remote add with other SSH port

Git On Custom SSH Port

What am I doing wrong? Am i using the wrong command? I've tried many of the commands in the related answers above, still no luck.

In short you can't change the port on which the remote service is listening. You are trying to use non-default port 12345 with github.com This is not going to fly. Also changing stuff in /etc/ssh/sshd_config is totally irrelevant here. It changes the behavior of your sshd (i.e. if someone tries to ssh or git@ssh to your machine).

Btw. you can test your ssh connection to github w/ this one-liner:

ssh -T [email protected]

Note that any non-default port will hang the connection (ssh -T [email protected] -p 12345)

First, if you want your ~/.ssh/config to be taken into account, your SSH URL should be

github.com:username/project-web.git

(no git@, no :12345)

Second 12345 would only work with a reverse proxy, which would then redirect to port 22 or 443 (when "Using SSH over the HTTPS port").
Regarding port 443, the Hostname would then be ssh.github.com.
