When clicking the button to download the archive (zip, tar.gz, etc), the response is a 502. The logfile /var/log/nginx/gitlab_error.log gives:
2016/05/04 08:01:56 [crit] 26087#26087: *3222164 connect() to unix://var/opt/gitlab/gitlab-workhorse/socket failed (13: Permission denied) while connecting to upstream, client: xx.xx.xx.xx, server: gitlab.domain.com, request: "GET /project/project/repository/archive.zip?ref=master HTTP/2.0", upstream: "http://unix://var/opt/gitlab/gitlab-workhorse/socket:/project/project/repository/archive.zip?ref=master", host: "gitlab.domain.com", referrer: "https://gitlab.domain.com/project/project/tree/master"
I’m not sure where to look. Nginx configuration for handling (using the server’s Nginx, configured as described here)? Linux file permissions and if so, which? Something else? Since the workhorse is triggered, I assume Nginx is configured ok.
