502 with nginx
When using the config for nginx with SSL, I get 502 (by nginx, not by gitlab-rails). The nginx log has the following:
2017/09/19 20:57:06 [error] 6086#6086: *1 connect() to unix:/var/opt/gitlab/gitlab-workhorse/socket failed (111: Connection refused) while connecting to upstream, client: CLIENT_PC_IP, server: OUR_GITLAB_FQDN, request: "GET / HTTP/1.1", upstream: "http://unix:/var/opt/gitlab/gitlab-workhorse/socket:/", host: "OUR_GITLAB_FQDN"
System: Debian 9 x86_64 nginx 1.10.3 Gitlab 9.5.5 (omnibus)
