'unauthorized' when trying git push

[Alashazam]

Hello,

I have setup a repository with access from 2 laptop

one works fine, and the second with a second account cannot perform a git push

and returns this message:

Unauthorized
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

The account has 'write' access to the repository, and an access key setup

ssh is working 

$ ssh -T git@bitbucket.org
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled

$ git --version
git version 2.27.0.windows.1

what did I do wrong?

It took me a while, 

But I fixed it, the problem was that my gui git was too old

So I have updated to latest Git for Windows v2.43.0

(incidentally, then was impacted by this other issue

but once this was fixed, the git push worked as expected
