Running Cells behind a Nginx reverse proxy

Created on 2019/04/18, nginx

This how to will give you all the hints with a simple configuration allowing you to run Pydio Cells behind your Nginx reverse proxy.

Specific Cells parameters

During your Pydio Cells installation (actually at the beginning) you will be prompted for 2 important parameters:

  • Internal Url: is the url used to bind your cells to the server.
  • External Url: is the url used to access your cells from outside.

So in our case for the reverse proxy, we must pay extra attention to External URL as it has to match the address of our reverse proxy that is going to be used to access Cells.

For instance we have Cells ( and the Reverse proxy ( running on 2 different machines(servers, etc...).

Cells Server Reverse Proxy Server

Therefore on you Cells Server we use the following values upon installation (assuming that we want to run Cells on port 8080), we also want to access the Cells instance through port 80 of the reverse proxy.

internal url external url

Now that we are all set let's take a look a the reverse proxy configuration.

Nginx reverse proxy configuration

This is a basic configuration that you can use and modify to meet your needs.

server {
        listen 80;
        listen [::]:80;
        client_max_body_size 200M;
        server_name reverse.proxy;

        location / {
                proxy_buffering off;
                #proxy_pass_request_headers on;
                #proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;

        location /ws {
                proxy_buffering off;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;

        error_log /var/log/nginx/cells-proxy-error.log;
        access_log /var/log/nginx/cells-proxy-access.log;


As you can notice the proxy_pass is the internal_url.

Then once you restart your Nginx, you can go to and you will have access to Pydio Cells.
