I have already read all existing topics. The topic posted Feb 25 seams to have a setup that mostly resembles my own which is: Unraid \> Nginx. This issue was solved by changing from Nginx to traefik and I don’t want to do that.

I am running Unraid 6.9.2. I’ve installed pydio cells. It is working and I can reach it on an external URL: [https://pydio.mydoman.com](https://pydio.mydoman.com).

I installed the CellsSync client on Mac - BigSur.

When I Create a Sync task - Connects to site BUT the TARGET PATH says… server closed the stream without sending trailers.

**NGINX Setup:**  
Domain Names - [pydio.mydomain.com](http://pydio.mydomain.com)  
Scheme - https  
Forward Hostnam/IP - [mydomain.com](http://mydomain.com)  
Forward Port - 8181  
Websockers Support - ON

**SSL Cert:**  
[pydio.mydomain.com](http://pydio.mydomain.com)  
Force SSL - ON  
HTTP2/ Support - ON  
HSTS Enabled - ON  
HSTS Subdomains - ON

Newbie - need help setting up CellsSync. All logs can be provided.

Hi, did you check [Running Cells behind a Nginx reverse proxy | Pydio](https://pydio.com/en/docs/kb/deployment/running-cells-behind-nginx-reverse-proxy) ?  
You may have to enable the grpc\_pass instruction in your nginx

Thanks Charles…

### Cells Sync

**Mandatory section for the Sync Client to work behind a Nginx reverse proxy.**

If your Cells Server is running behind a Nginx reverse proxy you must meet 2 requirements and then add the config below to your main nginx reverse proxy configuration.

- You need TLS encryption between Cells and Nginx.
- HTTP 2 need to be enabled like this `listen 443 ssl http2;` .

**Not sure how to complete the following steps.**  
Unraid NginxProxyManager - allows me to set up SSL using HTTP2.

I am not sure how to confirm TLS encryption between Cells and Nginx exist  
I need to know how to add the config below to your main nginx reverse proxy configuration. When it says “main nginx” is there a top level file OR do they mean to the pydio cells config file?

Hi, I don’t know Unraid … And not sure to understand your question.  
Cells does not ship its own nginx : so when we are talking about the nginx configuration, it’s about your own nginx proxy.

Thanks for the help… sorry to confuse, I wasn’t sure what config file to change but I don’t think that is my issue. The nginx file is correct.

thanks again for the attempt.
