White screen when accessed via NGINX reverse proxy


#1

Hey everyone!

Recently decided to install Rocketchat as a Slack alternative for my friends and I, but I’m getting a white screen whenever I attempt to access the server via https through NGINX (It will still show the updated name of the server in the title bar, though). What am I missing?

You can see the output here: beard.jumpingcrab.com/rocketchat

Here’s my setup:

  1. NGINX running in Freenas jail so I can supply multiple jails/VMs with SSL. (Set up pretty much like this: https://forums.freenas.org/index.php?threads/how-to-set-up-nginx-to-reverse-proxy-your-jails-w-certbot.49876/). Cert is valid and done and tests at SSL labs to an “A+” rating.

  2. NGINX has its configuration and a proxy_setup redirecting from my domain to 192.168.1.3:3000 (my internal VM with the Rocketchat snap installed on it). Automatically redirecting to HTTPS.

I’m able to access my Rocketchat server from 192.168.1.3:3000, and I’m also able to access from my public IP, no issues.

When I attempt to access via my domain and reverse proxy, all I get is a white screen. The title of the server appears just fine at the top and is updating if I change it from the internal IP.

So, not sure what I’m missing here. Do I need NGINX on the Rocketchat server as well, or something weird like that?

Please help!

Thanks for posting. Did a copy paste and modified for my domain. Can still reach it and white screen is still there:

If I do an inspect on the page, I get this:

I’m confused as to why it can’t find these items through the proxy…

@dctheee are you following this section of the docs for running off a “sub folder”?
