git push origin master Missing or invalid credentials

Cannot push anymore to origin master, git push origin master , since a few days, I have uninstalled git and Visual Code and reinstalled it but nothing, I’v got same error :

Missing or invalid credentials.
Error: socket hang up
    at connResetException (internal/errors.js:559:14)
    at Socket.socketOnEnd (_http_client.js:433:23)
    at Socket.emit (events.js:208:15)

    at processTicksAndRejections (internal/process/task_queues.js:77:11) {
  code: 'ECONNRESET'
}

I do not understand this behavior, because on my other computer everything works, and no GitHub files are corrupted.

here is my configuration : Ubuntu 18.04.4 LTS

Need some help please !

The error states Missing or invalid credentials.

I would check just that, making sure that both computers have exact same github credentials.

You could try to run this.

git config --global credential.helper store
