Mi pregunta es: ¿Qué significa este error o qué hago mal?

Intenté recrear la aplicación openshift. Y revise mi contraseña en mi file .travis.yml .

Lo git push -f openshift master inicial desde mi repository git push -f openshift master local git push -f openshift master

.git / config

 [remote "openshift"] url = ssh://527aafeb5973caf4e90007ca@audioblog-l33tname.rhcloud.com/~/git/audioblog.git/ fetch = +refs/heads/*:refs/remotes/openshift/* 

Y ahora se despliega nuevamente, pero aún me interesa saber por qué sucedió esto.
