GitLab Pages NGINX reverse proxy config


I’m running GitLab omnibus on Ubuntu 20.04 with unbundled NGINX and I’d like to allow users of my installation to use GitLab pages, however I can’t get it to work. I’ve tried proxy_pass localhost:8090 from:
##! Listen for requests forwarded by reverse proxy
gitlab_pages[‘listen_proxy’] = “localhost:8090”

(obviously with proxy_pass off), but that gives me a 502 bad gateway error. I also tried to just copy the NGINX config I use for GitLab itself (wasn’t really expecting it to work but it was worth a try) and that obviously didn’t work as well.

What am I doing wrong in the config? Is my setup even supported for GitLab pages?
