reason:

The user name and password configured by local git are inconsistent with those registered on gitlab.

Solution:

If the account and password are changed, execute the following commands on the GIT command line

git config --system --unset credential.helper

Then re execute your operations (such as pull and push), and you will be prompted to enter your account and password again.

What’s your feeling?

In retrospect, it seems that I did create a new user name and password, or I changed my password. ok
