sorry but I'm confused - why is this issue closed?

[landcraft]

understood. any tips on how to uncover the issue? I'm really at a loss...

Hi @landcraft, I would debug nginx, What do its logs say? Of course this is off topic on paperless-ng discussion but I would start from there.

[landcraft]

OK thanks - will try that

[landcraft]

you were right - it was an nginx config issue. thanks!

Glad to hear that, mark the most useful answer here as "the answer", so people will see that your question has been answered.

@landcraft - Would you be willing to share your swag config for paperless-ng that you got working? I haven't been able to get this to work and would love to see what a working version looks like to see what I'm messing up.

[landcraft]

Sure, I'll dig it out when I get home

Thank you! I appreciate you looking into this. I wasn't sure I'd hear back since the original thread is so old.

Hope it helps:

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name paperless.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    location / {

        include /config/nginx/proxy.conf;
        resolver 127.0.0.11 valid=30s;
        set $upstream_app paperless;
        set $upstream_port 8000;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
    }
}

That worked. Thank you! I think I had a little too much extra configuration based on the wiki page it has about adding in some proxy_set_headers for WebSockets.
