ssh issue after repositosy name change

I changed name of my repository to https://bitbucket.org/gkt/variable-length-video-prefix-caching. After that I am unable to push to it.
{{

{\\ #!shell git push -u git@bitbucket.org:gkt/variable-length-video-prefix-caching.git master\\ ssh: connect to host bitbucket.org port 22: Connection timed out\\ fatal: The remote end hung up unexpectedly }

}}
