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

Issue

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
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Connecting to github.com [140.82.112.4] port 22.
debug1: Connection established.
debug1: identity file /c/Users/Administrator/.ssh/id_rsa type 0
debug1: identity file /c/Users/Administrator/.ssh/id_rsa-cert type -1
debug1: Local version string SSH-2.0-OpenSSH_8.3
debug1: Remote protocol version 2.0, remote software version babeld-25270101

debug1: Authenticating to github.com:22 as 'git'
debug1: SSH2_MSG_KEXINIT sent
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?

Solution

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.
