How to fix Connection reset by 140.82.112.4 port 22 for git local connection to github remote?-CodePudding

My local computer is using win10, gitbash client, before the local repository and github remote repository can communicate normally via ssh in both directions(pull/clone or push etc), but this time when I pull the remote code to update locally, I get an error.

git pull origin main
Connection reset by 140.82.112.4 port 22
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

I then tried the following command to see if it worked.

 ssh -vT [email protected] -A
OpenSSH_8.3p1, OpenSSL 1.1.1g  21 Apr 2020
debug1: Reading configuration data /c/Users/Administrator/.ssh/config
debug1: /c/Users/Administrator/.ssh/config line 2: Applying options for github.com

Connection reset by 140.82.112.4 port 22

It was also tested using the following command.

ping github.com

Also I have tried regenerating the ssh key and then copying the public key correctly into the ssh configuration of my GitHub account as well, the local computer .ssh/config file reads as follows

  Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa
  ForwardAgent yes

The result is still unsuccessful.
Does it seem to be connected properly? What can I do to fix it?

CodePudding user response：

ssh -vT [email protected] -A: you are not supposed to use agent forwarding with github.com itself.

The test should be:

# Attempt to SSH in to github
  ssh -T [email protected]
> Hi USERNAME! You've successfully authenticated, but GitHub does not provide
> shell access.

Check the "Using SSH agent forwarding" documentation and see if it applies to your case.

Note: /c/Users/Administrator/.ssh/config: it is best practice to not use your Windows Adminnistrator account, but rather your personal named account with which you initially logged to your Windows session.
