fatal: unable to connect to github.com: github.com[0: 140.82.121.4]: errno=Unknown error

Question

I'm having a problem with my Git account. Every time I execute git push, I get the following error:

I discovered that I'm working with an SSH URL:

I tried switching back to an HTTPS URL using the following commands:

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

However, it doesn't seem to change anything:

I tried many options that I thought were solutions such as manually configuration of config file but nothing works.

Answer 1

This error occurred because your git port is restricted.

You can get it fixed with the following command:

git config --global url.https://github.com/.insteadOf git://github.com/

By doing this globally it will also repair other issues where perhaps old repositories or other scenarios may be using git instead of https when the git:// port/protocol may not be functional now vs earlier.

Answer 2

To use git with ssh, a different url syntax is needed, with git@<url> as url. According to your screenshot, the url should most likely look like this

[email protected]:ahlemtbini/blog_web.git

You can change it with the following command

git remote set-url origin [email protected]:ahlemtbini/blog_web.git

If you are using github, i recommend you to always use the url's listed under the code-button at the github-page of that repository. More information here
