“remote: GitLab: API is not accessible”

I use to have my gitlab (Version 7.7.2) server on AWS. I have moved this to local VM running Ubuntu 14.04 and gitlab (Version 7.7.2)
I took the gitlab backup on AWS EC2 using the command:
sudo gitlab-rake gitlab:backup:create

then I copied this file to local VM and restored using following command
sudo gitlab-rake gitlab:backup:restore BACKUP=<>

Everything was restored without any error. Now when users are trying to Push to the repositoriesthey get following error:

“remote: GitLab: API is not accessible”

What am I missing?

Thanks for helping me.
