Take github as an example, I found this article:
https://help.github.com/articles/error-bad-file-number/
First test using the following command: ssh -vT git@github.com Discover more error messages.

Then combine the error message you see now:

ssh:connect to host github.com port 22:Bad file number
fatel;cound not read from remote repository.
please make sure you have the correct access rights
and the repository exists 

Maybe it’s a permissions issue,
1. Try to upload the public key to github
2. The remote repo does not have enough permissions?

GIT setup problem:
First step:
Settings

git config --global user.name "你在githbub上注册的名"

git config --global user.email "你在githbub上注册的电邮"

Step 2: Authorization, assuming you use SSH to connect

The third step Create the library, this is done on GITHUB, no need to repeat it

When you are local

git commit

Then, just

git push 

You see the prompt' git remote add <name> <url>'
Then, you

git push

Too much to say, if you look at the English help, it’s all in there
git configuration

You should add a config file in the .ssh directory to set port 443
