The hexo blog that can be run locally, when pushing to github

prompts that the public key authentication failed

But testing

Not sure what this is. . . Other repositories can also submit code normally
Or where should I go to check the problem
This is the git configuration in _config.yml

deploy: 
  type: git
  message: update
  repo: 
    github: git@github.com:Can2studio/Can2studio.github.io.git,master
    can2: ssh://can2@git.kdwycz.com:2333/git/can2/blog.git,master

Thank you very much orzzzz! ! ! !
