Remote access with Docker

[mwav3 (Tim)]

It appears your nginx config is not properly setup for websockets which home assistant relies on to connect/stay open.

See my sample config here, the important thing to add I believe are these lines to “upgrade” the connection and keep websockets open.

location /api/websocket {
        resolver 127.0.0.11 valid=30s;
        set $upstream_app homeassistant;
        set $upstream_port 8123;
        set $upstream_proto http;
        proxy_pass http://192.168.0.184:8123;

        proxy_set_header Host $host;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

Its probably just the default NGINX default conf file. A lot in what you posted looks different then mine. You can try mine if it helps. Just replace your “mydomain.duckdns.org” with your actual duckdns domain and the IP address under Home Assistant with your actual machine’s IP address. Leave all the other IP references alone as those are loopbacks within the Swag container itself (for fast CGI and resolver) ## Version 2020/05/23 - Changelog: https://github.com/linuxserver/docker-swag/comm…
