Jenkins, an open-source automation server, performs a crucial role in continuous integration and continuous delivery (CI/CD) processes. It can be integrated with version control systems like GitHub to automate the development, testing, and deployment of software projects. However, when you face status code 128 while interacting with GitHub through Jenkins, it can be a puzzling problem. In this article, we will explore what this status code means, its potential causes, and steps to troubleshoot and resolve this issue.
What are Status Code 128 ?
A status code 128 in the context of Jenkins and GitHub normally indicates the issue faced during authentication or authorization. GitHub uses personal access tokens, SSH keys, or username/password combos for authentication, and any failure in this process generally leads to the status code 128 which must be resolved for proper functioning.
What are the Causes for Status Code 128
1. Incorrect Credentials
- Ensure that the credentials used in Jenkins for GitHub access are correct and valid. This consists of personal access tokens, SSH keys, or username/password combinations.
- Check for typos or discrepancies in the credentials, as even a small error can cause authentication failures.
2. Token Expiry
- GitHub private access tokens have an expiration period. If the token used by Jenkins has expired, it’ll bring an authentication issue.
- Regularly update and rotate personal access tokens to avoid expiration-related issues.
3. Insufficient Permissions
- Verify that the account associated with the provided credentials has the necessary permissions to access to the repositories and perform the required action on it.
- GitHub repository permissions would possibly have changed, to make sure the Jenkins user has the required access.
4. Firewall or Proxy Issues
- Network configurations, firewalls, or proxy settings are probably blocking Jenkins from reaching GitHub.
- Ensure that the necessary ports are open and they do not have any network restrictions.
Prerequisites
Before troubleshooting Jenkins status code 128 with GitHub, make sure the following conditions are met:
- Jenkins Installation: Jenkins should be set up and configured effectively on your server. Follow the official documents for set up or Installation Process.
- GitHub Account: You need a GitHub account with access to the repositories that are involved with your Jenkins job.
- Jenkins Credentials: Verify that the GitHub credentials in Jenkins are correctly configured with the personal access token or appropriate authentication method.
- Network Access: Ensure that the Jenkins server has proper network access to reach GitHub. Check firewall and proxy configurations to avoid network-associated issues.
- Repository Permissions: Confirm that the Jenkins user or the consumer related to the credentials has the specified permissions (Read, Write) within the GitHub repositories.

Troubleshooting Common Issue with Status Code 128
You can itself troubleshoot the common issues that occur with status code 128 by these following points:
1. Check Jenkins user permissions:
You must verify first that the user Jenkins have read access to the necessary Git configuration files. Access permission issues sometimes cause this error.
2. Check Jenkins logs
Look for detailed error messages in the Jenkins logs ,you can generally find it under Manage Jenkin section ( “Manage Jenkins” -> “System Information” -> “Logs”). This might can provide clue about the connection issue
3. SSH key issues
If you’re using SSH authentication, make sure that the key configured in Jenkins matches with the authorized key in your GitHub account. Incorrect or missing keys can lead to status code 128.
4. Network connectivity:
Make sure Jenkins have network access to GitHub. Firewall restrictions or network issues may impact the connection.
Conclusion
If you are encountering Jenkins returned status code 128 with GitHub it can be a problematic issue, but by understanding the main reasons behind it and following the troubleshooting steps mentioned in this article, you could successfully address and solve the authentication or authorization problems. Maintaining proper credentials, staying aware of token expirations, and verifying permissions are key practices to make certain a smooth integration between Jenkins and GitHub for your CI/CD pipelines.
