fatal: unable to connect to github.com: github.com[0: 140.82.121.3]: errno=Operation timed out

Question

I try to push my project and it shows me this in the terminal (I use MacOS): fatal: unable to connect to github.com: github.com[0: 140.82.121.3]: errno=Operation timed out

I tried to clone a project and it showed me that, then I tried to push one in my personal GitHub and it showed it again. Before trying to clone the project it worked well. Idk why is this happening.

joanskenderi@joans-mbp Course Goals App % git push origin master
fatal: unable to connect to github.com:
github.com[0: 140.82.121.3]: errno=Operation timed out

joanskenderi@joans-mbp Course Goals App % git remote -v
origin  git://github.com/joanskenderi/Course-Goals-App.git (fetch)
origin  git://github.com/joanskenderi/Course-Goals-App.git (push)
joanskenderi@joans-mbp Course Goals App %

Can you edit your question to include a code block with the output of git remote -v? – Kingwood

I think I did it. @Kingwood – Cleopatracleopatre

Answer 1

The problem here is that you're using the unauthenticated Git protocol on port 9418 (that can be seen with git://). GitHub turned that off sometime back because it's unencrypted and can be tampered with by pretty much anybody.

Even when it was supported on GitHub, you were never able to push with it because there was no way to authenticate.

You need to change the remote URL to either HTTPS or SSH, like so:

$ git remote set-url origin https://github.com/joanskenderi/Course-Goals-App.git
# or
$ git remote set-url origin ssh://github.com/joanskenderi/Course-Goals-App.git

It's best to use the one for which you already have credentials (either a personal access token or an SSH key) set up.

Answer 2

The problem was the git port is restricted.

I fixed this with:

git config --global url."https://".insteadOf git://

Answer 3

I was having the same error. Following the first answer from @bk2204, this worked for me:

$ sudo git clone https://github.com/joanskenderi/Course-Goals-App.git

Answer 4

Use url in .submodule file in this format:

[submodule "submodule-name"]
    path = my-folder
    url = [email protected]:My-User/my-repo.git

Don't forget to:

git submodule sync 
git submodule update

Works well for me. But I'd avoid submodules in general ;)

Answer 5

Yeah Using https:// protocol instead of git worked for me.
