[knelyo]

Greetings team,

   I am getting the error below during the build of a Jenkins pipleline job that only does validation of templates for sensitive data..

   The pipeline was working before but it just stopped working and it reporting the error below...

   The Tech stack version.

    Jenkins  2.164.3

    GitLab   Community Edition 11.3.0

    GitLab plugin. 1.5.12

 One thing i want to mention is that the jenkin is able to check out the git repo in gitlab with out error. and then fails error below.

  One error that is a bit concise is from the open blue ocean plugin " org.gitlab.api.GitlabAPIException: {"message":"403 Forbidden - Your account has been blocked."}

Issue resolved..

The error was miss leading, the fix was related to user credential in gitlab, A new token of  "API" type was generated in Gitlab and the new token was updated in Jenkins for the same. this steps resolved the issue.

Thanks
