Gitlab unicorn webserver either does not listen or reply on 8080

Question

GitLab can be started and shows as running. When running curl git.myserver.com, this fails with HTTP 503. No interesting entries in the unicorn.stderr.log or unicorn.stdout.log.

Versions:

• GitLab 6.5.1
• Apache 2.4.6
• Ubuntu 13.10

Answer 1

Solved. I had used Ruby 2.1.0 while the install guide tells to use Ruby 2.0.0. Closely re-installed and restored the backup, which now works perfectly.
