Bitbucket logs show:

1 Unexpected response received. Status code: 401

Cause

This is caused by third-party plugin Yet Another Commit Checker.

Solution

  1. It is recommended to revisit the plugin configuration for the affected repository.

  2. Also, you may want to either look to upgrade this plugin if possible and see if that resolves the issue, or that you look to disable this plugin entirely.

  3. Otherwise, you can consult with the support resources for the vendor of this plugin for assistance with this behavior, as this is not something that was created or is maintained by Atlassian.
