MediaCMS does not work properly behind a reverse proxy

[Mozitux]

Describe the issue
Hello, I self-host my servers and to do this I use port forwarding and a reverse proxy.

I noticed that the home page does not display when going through the proxy address, same for user profiles or uploading videos, there is an infinite loading screen.

As soon as I go back to the local ip or the public ip, everything works correctly, how can I fix the problem? Is there an additional port to open besides port 80 and 443?

To Reproduce
Steps to reproduce the issue:

1. Make a MediaCMS server behind a reverse proxy
2. Load the home pages, user's profiles or try to upload a video
3. See error

Screenshots

Environment (please complete the following information):

• OS: Proxmox 7.2 (Debian OS based)
• Installation method: Single server
• Browser: I've tried Firefox and Edge

Other
I use Apache2 for the reverse proxy

These two missing lines in the settings.py fixed it for me.

USE_X_FORWARDED_HOST = True
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

These lines instruct django to use the forwarded headers from the reverse proxy

@JustinBack Hello, thank you!
Unfortunately it doesn't seem to work for me, I enter the two lines in this format, is it correct? (I've tried just copy/pasting and it doesn't work)

USE_X_FORWARDED_HOST = True
SECURE_PROXY_SSL_HEADER = ('http://not-youtube.com:2080', 'https://not-youtube.com:2443')

Hi!

Keep the lines as is in my comment above, don't change anything and it should work properly :-)

Edit: Just saw that you tried the original one as well. Is nginx properly setting the x-forwarded-host and x-forwarded-proto header?

I'm not familiar with nginx, how can I check this?

Are you running the dockerized nginx proxy or running a locally installed nginx? I removed the dockerized nginx proxy as it caused a couple of issues but here is my nginx config:

server {

	server_name my.server.tld;

    client_max_body_size 5G;
    charset utf-8;
    
    location / {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto https;
        proxy_pass http://localhost:8012; # 8012 being the forwarded port of the web container in docker
    }

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/my.server.tld/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/my.server.tld/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot




}

server {
    if ($host = my.server.tld) {
        return 301 https://$host$request_uri;
    } # managed by Certbot



	server_name my.server.tld;
	

    listen [::]:80;
    listen 80;
    return 404; # managed by Certbot




}

Hello, I'm running locally installed nginx and use an Apache2 revert proxy
What file is this from?

[Mozitux]

Here is a diagram of my reverse proxy configuration:

Hi,

when your Browser Console responds something like this

you can try adding the following lines to your Apache Site Config:

RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"

That worked for me.

Heres my full config file:

<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName [domain]
ProxyPreserveHost On
DocumentRoot /var/www/html
ProxyPass /.well-known !
ProxyPass / [URL of MediaCMS Server]
ProxyPassReverse /  [URL of MediaCMS Server]
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"
[Let's Encrypt Settings]
</VirtualHost>
</IfModule>

Unfortunately, it only works if you are logged in. I have written more about this here: #502

HI there, same issues here with a nginx proxy manager (reverse proxy) and a new ubuntu 20 stand alone server/install based on this tutorial.

https://theitguycj.com/self-host-and-share-your-videos-audio-and-pictures-with-mediacms/

my current setup is showing the same half broken pages https://media.bluegoat.ca

i tried adding ALLOW_ANONYMOUS_ACTIONS = [] to local_settings.py and restarted. no change.

Just wanted to say Thank You to JustinBack. Your additional two lines (as he has them printed) and your reverse proxy config alleviated issue of links not working. Now if I can just get uploaded video to play back through the proxy I will be set!
