Version-manager with AzureDevOps git

Is anyone using the git repo that is available in Azure DevOps ( ADS )?  Our dev team uses git that is available through Azure DevOps for main source control system.  I've done a version-management POC for our Appian Development team using GitLab and now I'm trying to see if we can utilize our git server on ADS.  We are running into authorization errors when trying to a simple command of updateLocalRepo.  I've added user name and password into the version-application.properties.  

Looking for any wisdom on where to look or solutions.  

Thanks
