[...]Cause
There are a few possible causes:
Incorrect credentials for authentication
Your Bamboo proxy is misconfigured
Gitlab is configured to require 2FA authentication
The Gitlab account does not have an SSH key set up
Solution
Incorrect credentials for authentication
Please make sure that you are using the correct username and password to authenticate against the repository. You can test the credentials outside Bamboo to be sure they are correct by running Git operations (clone i.e.) against the desired repository.
Your Bamboo proxy is misconfigured
A misconfigured proxy in front of Bamboo can cause issues with Gitlab communication. All details and steps to fix that is described in the following article:
Gitlab is configured to require 2FA authentication
If your Gitlab instance has two-factor authentication (2FA) enabled, please note that personal access tokens (PAT) are required, meaning you'll need to create a PAT for the Gitlab account and use it in Bamboo to to connect with Gitlab. More information is available in the following Gitlab documentation:
The Gitlab account does not have an SSH key set up
A GitLab account needs an SSH key in order for Git operations to be allowed, and that can impact the connection with Bamboo. If that's the case, you'll see the following banner at the top of the screen while accessing a Gitlab project:
Please make sure to add at least one SSH key to theGitlab account so that Gitlab doesn't block connections.
