Have you enabled WebSocket proxy?
Is that in Traccar?
No, in your proxy.
I just added WEBSOCKET_ENABLED to my docker variables, still no data. It also keeps making me reregister every once in a while.
Not sure where I would put that in my proxy conf. I mostly use existing templates. My current conf for traccar looks like this.
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name traccar.*;
    include /config/nginx/ssl.conf;
    client_max_body_size 0;
    # enable for ldap auth (requires ldap-location.conf in the location block)
    #include /config/nginx/ldap-server.conf;
    # enable for Authelia (requires authelia-location.conf in the location block)
    #include /config/nginx/authelia-server.conf;
    # enable for Authentik (requires authentik-location.conf in the location block)
    #include /config/nginx/authentik-server.conf;
    location / {
        # enable the next two lines for http auth
        #auth_basic "Restricted";
        #auth_basic_user_file /config/nginx/.htpasswd;
        # enable for ldap auth (requires ldap-server.conf in the server block)
        #include /config/nginx/ldap-location.conf;
        # enable for Authelia (requires authelia-server.conf in the server block)
        #include /config/nginx/authelia-location.conf;
        # enable for Authentik (requires authentik-server.conf in the server block)
        #include /config/nginx/authentik-location.conf;
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app traccar;
        set $upstream_port 8082;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
    }
}
Turns out I needed to turn the service off and back on in the phone app and it started working
I have Traccar running in docker on a Linux machine and am trying to reverse proxy it through NGINX (Swag) and I can reach the UI through my domain. I installed the client app on my phone and set the domain to
https://traccar.mydomain.xyz. I then added the phone in the server using the identifier supplied in the app. I am not however seeing the device being tracked in the UI. Any help would be appreciated.
