          The same git repository and credentials works fine for a single maven project. Could it be because private gitlab configurations? unfortunately I don't have an access for gitlab server. but as it works for single maven project and doesn't for multi branch I consider it as a bug.

          Thanks a lot for a help!
          best regards,

          I have a feeling this is similar JENKINS-33021. If I update my server to have weaker algorithms, the connection works. This is not a problem when using the git plugin directly, it only happens when using the "Multi-branch" plugin. I'm not sure why this plugin isn't using the git plugin as a dependency directly, but that appears to be the case since the git plugin by itself works.
