Answer 1

Execute:

nc -v -z <git-repository> <port>

Your output should look like:

"Connection to <git-repository> <port> port [tcp/*] succeeded!"

If you get:

connect to <git-repository> <port> (tcp) failed: Connection timed out

You need to edit your ~/.ssh/config file. Add something like the following:

Host example.com
Port 1234

When I accidentally switched to a guest wifi network I got this error. Had to switch back to my default wifi network.

Answer 3

Basic URL Rewriting

Git provides a way to rewrite URLs using git config. Simply issue the following command:

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

Now, as if by magic, all git commands will perform a substitution of git:// to https://

source: git:// protocol blocked by company, how can I get around that?

Answer 4

The reason could be the firewall modification as you are under a network.(In which case they may deliberately block some ports)
To double check if this is the reason ... do

ssh -T git@github.com

this should timeout. If that's the case use http protocol instead of ssh this way
just change your url in the config file to http.
Here is how :-

git config --local -e

change entry of

 url = git@github.com:username/repo.git

to

url = https://github.com/username/repo.git

Answer 5

The main reason was the change from the proxy installed by the company recently, which has blocked other ssh connections other than those to the company domain.

I was able to connect successfully by following these steps:

1. Double checked that the issue is what I am assuming by ssh -T git@github.com

It should end up in a timeout.

2. Edited the local remote URL by

ssh config --local -e

and from

url=git@github.com:asheeshjanghu/Journal.git

to

url=https://github.com/asheeshjanghu/Journal.git

The important point is that in the url you have to change at 2 places.

from git@ to https:// and from github:username to github/username

In the end verify by doing a git fetch
