Deployment to Azure web app display Error: fatal: Authentication failed for 'https://xxx.scm.azurewebsites.net:443/xxx.git/'

I am trying to deploy my node.js application to azure web app using Azure App Service management extension via vs code.
I succeeded to deploy this application many times until two days ago.
Since then I am getting the error log:

WARNING: Ignoring deploySubPath "." for non-zip deploy.
xxx: Starting deployment...
xxx: Deploying Local Git repository to "xxx"...
Error: fatal: Authentication failed for 'https://xxx.scm.azurewebsites.net:443/xxx.git/'

At the Azure portal under the Activity log I am getting:
Operation name: Publish Web App
Status: Succeeded

However, At the Deployment center -> Logs:
I cannot see the new deployment.

Any ideas for what should I do?
