Note** If you are using password for the authentication kindly validate the correct password is in use else, If the authentication is done via access token kindly check the validity of the access token used for authentication.

Resolution

The access token for the GitLab repository is expired and needed to be regenerated. Once it is updated, the synchronization mirror will start working.
