2 days ago I noticed my daily system test jobs started failing due to being unable to clone my jenkins script repo. I am using credentials for a bot user, that are valid. I can log into the bots github user account no problem, but using the following checkout stage…

```auto
        stage('Pull jenkins scripts') {
            steps {
                checkout scmGit(branches: [[name: '*/develop']], extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'jenkins']], userRemoteConfigs: [[credentialsId: 'company-github-creds', url: 'https://github.com/company/jenkins.git']])
            }
        }

```

results in the following error

```auto

I had upgraded to 2.462.3 on the 12th October. Builds were fine until the 23rd, and now none of my builds that use the gitSCM plugin will authenticate. I am really not sure where the problem lies?

Not sure what the issue is but there is a get around for anyone else that has encountered this issue. Use the bots github token…

```auto
        stage('Pull jenkins scripts') {
            steps {
                withCredentials([string(credentialsId: 'github-token', variable: 'GITHUB_TOKEN'), string(credentialsId: 'github-bot-user', variable: 'GITHUB_USER')]) {
                    dir("jenkins") {
                        git url: "https://${GITHUB_USER}:${GITHUB_TOKEN}@github.com/company/jenkins.git", branch: 'develop'
                    }
                }
            }
        }

```

And when you want to pull from a tag instead of a branch

```auto
            steps {
                withCredentials([string(credentialsId: 'github-token', variable: 'GITHUB_TOKEN'), string(credentialsId: 'github-bot-user', variable: 'GITHUB_USER')]) {
                    dir("jenkins") {
                        checkout([
                            $class: 'GitSCM',
                            branches: [[name: "refs/tags/v1.0.0"]],
                            doGenerateSubmoduleConfigurations: false,
                            extensions: [],
                            submoduleCfg: [],
                            userRemoteConfigs: [[
                                url: "https://${GITHUB_USER}:${GITHUB_TOKEN}@github.com/company/jenkins.git"
                            ]]
                        ])
                    }

```
