GitLab version: 11.6.0-ee (4c09765c642) Omnibus Today, we tried to configure our corporate proxy server like it is [described in the docs](https://docs.gitlab.com/omnibus/settings/environment-variables.html). This caused project pages (GitLab returning a 503 error page) and other functionality depending on communicating with localhost to be unavailable. The no_proxy variable still seems to be ignored, despite it should [work as of GitLab 11.6](https://gitlab.com/gitlab-org/gitlab-ce/issues/17587)? But that is another issue. Though, the docs should probably give a hint. ##### The issue Reverting the configuration changes done to gitlab.rb does not delete the environment variables defined previously. ##### Workaround Delete the files at `/opt/gitlab/etc/<service>/env/<variable>` by hand and restart GitLab with `gitlab-ctl restart`.
